深渊信使 — Abyss Messenger（https://abyss-messenger.gamestrategists.com）
这个子域上是浏览器里那一份《深渊信使：最后五封信》：一座 3D 的鲸背岛、五处地标（灯塔与码头、南边珊瑚礁、沉船湾、骨神殿、深渊实验室）、五封要按顺序送到五位收信人手里的信、四道要把两份证词对上的题、十二段能拾得的回声残片，以及四个结局。发布者是独立开发者 alphaBETA DEV（GameStrategists），一个人，不是公司。
另有两样东西不归本页管。一是主站 gamestrategists.com 上那些页面——这款游戏的厚页、攻略、更新日志——它们自己有一份服务条款；两份说法不一致时，以您正在玩的这一个子域为准。二是这一款没有第二个分发渠道：浏览器之外拿不到它。本项目的另外三作（《大金减肥GoGoGo》《404号房间》《小齐赢赢赢》）在微软商店有能离线运行的安装包，《深渊信使》不在其中，所以本站不存在「商店侧的安装、退款、内容评级」这类本页够不着、得由商店自己回答的事。
本作没有任何收费环节：不要注册、没有内购、没有付费章节，也没有需要绑定的支付方式。既然没有钱进来，也就没有退款这回事——「为了这一个结局走完全程值不值」这类争议在本站没有可处置的对象，既没人能退钱给您，也没人能替您撤销一个选择。
域名与托管是要花钱的，本站打算用页面上那条 Google AdSense 广告脚本带来的收入分摊它。游戏首页确实加载了一条 Google 的广告脚本（2026-11-02 线上三轮采样各 1 条），而游戏画面里那块留给版位的位置被一个开关挡在挂载之前，所以屏上不会出现一个本站摆着的广告框。同日真浏览器实测：标题屏与这张说明页上，写着「广告」二字的框各 0 个，包围盒面积大于 0 的广告容器各 0 个。进游戏之后，页面里会多出一个 0×0、不显示的广告容器——那是广告加载器自己插入的待机容器，屏幕上看不见它，也不是本站放的位子。投哪一条广告由广告网络决定，我们看不到，也没得选。广告如何选您、以及如何关掉个性化投放，写在 隐私政策 里，那一份才是管这件事的；投放状态一变，上面这一句跟着变。
还有一层要分开说：广告脚本只写在游戏首页那一份 HTML 里。2026-11-02 把五张页各打开三轮，逐条记下出站请求，两类页面不是一张表——
| 页面 | 出现的主机 | Cookie |
|---|---|---|
/（游戏首页） | 本站、pagead2.googlesyndication.com（三轮各出现）、static.cloudflareinsights.com（三轮各出现）；googleads.g.doubleclick.net 与它的探针 Cookie 在三轮里出现一轮 | 只有 test_cookie@.doubleclick.net 一条，且只在广告走到那一步的那一轮 |
/terms（本页）、/privacy、/about、/contact | 只有两个主机：本站与 static.cloudflareinsights.com。上面那几个广告端点在 12 次读数里 0 次出现 | 一个都没有 |
那条 Cloudflare 的 beacon 由托管平台随每一份 HTML 注入，与隐私无关的那部分只在聚合访问量与性能指标上；本页下面引用的每一个数字都来自这样一轮一轮的真实读数，不是抄另一份文案。
这一作没有「先签一份东西才放您进去」那一步：标题屏没有要求您勾选的框，也没有一个「同意」按钮。2026-11-02 用真浏览器实测，未交互时的标题屏上可见的按钮是两颗——「开始投递」（本机有档时这句变成「继续投递」）和右上角那颗语言切换。那张屏上还有回到五张说明页的入口（关于、联系、免责声明、隐私、条款），它们都在页脚那一行里。
本站也没有一段专门的健康警告屏，这一点如实写着：第一次打开时您看到的就是游戏本身。本作的题材是深海恐怖推理——三年前，您的哥哥林屿作为信使来到鲸背岛，留下五封没有寄出的信，走进海底泵站后再没有回来；您是林溪，带着他的路线本替他把最后这一趟送完。它的声音是低频为主的合成环境音，只在您真的按下「开始投递」之后才创建，在那之前本站连一个音频上下文都不存在，也不会向您索要任何权限；想安静地走完整段，标题屏之后右上角那颗按钮随时能关掉它。
这是一款单机作品：没有别的玩家，没有聊天，不向您索取任何身份信息。它不面向十三岁以下的儿童。
条款里几件常见的事，在本站一件都没有发生，所以也就没有对应的规则：没有账号，因此没有封号、没有申诉，也没有谁能「终止您的服务」；没有收费，因此没有退款流程；没有会收集您信息的表单、没有评论区、没有上传入口，也没有供别的程序调用的接口。游戏里确实有两个输入框——投递验证那一层的答题框，和结算屏里那个要您填频率的框——它们各自包在一张表单里，但两条提交路径都在浏览器里先拦下默认行为，再在本地比字符串：2026-11-02 从打开页面到进游戏、切语言、关声音整程走一遍，非 GET 请求 0 条，页面上的脚本报错 0 次。您敲进去的那串字符比完就丢，连存档都不进。
本站能对某个人做点什么的空间很小；反过来说，您在本机那一局也只有您自己能动。五单的状态、每一单拿到的评分、走过多少秒和多少距离，全部只写在这台设备浏览器里的三个键：abyss-save.v1（进度）、abyss-lang（您上次按语言按钮选的是中文还是英文）、abyss-sound（环境音是开还是关）。清掉它们有两条今天真能走到的路：结算那一屏的「重新投递」——它动手之前会先用浏览器自己的确认框把代价念一遍，告诉您要冲掉几个已经记下的评分——或者在浏览器里清除本站的站点数据。标题屏上另有一颗「从头开始」，实测它在页面上始终是隐藏的（原因与这条的处置都写在 隐私政策 里，那是个待修的缺陷，不是我们打算维持的设计），所以现在游戏内可达的清档入口只有结算那一屏那一个。
知识产权这一条沿用本站一直写的口径，没有新增也没有收回：除另有说明外，站内文字、图片、代码、游戏设计与故事内容的版权归 alphaBETA DEV（GameStrategists）。未经书面许可，不得复制、修改或再分发。想用在别处，写信到 contact@gamestrategists.com 问一句，说清想用在什么地方、打算怎么署名就行。
robots.txt 放行 User-agent: *、Disallow 一条都没有，另外逐条点名允许九个 AI 与生成式检索抓取器（Google-Extended、GPTBot、ChatGPT-User、ClaudeBot、anthropic-ai、CCBot、Omgilibot、PerplexityBot、Applebot-Extended），并声明本站自己的 sitemap。这一页的旧版写过「不使用自动化工具批量抓取本网站内容（搜索引擎爬虫除外）」——那句和它自己站点上的 robots.txt 打架（2026-11-02 实测：Disallow 0 条、具名放行 9 条），所以这一版换成上面这一句。点名放行是为了让人找得到这款游戏、让摘要能引用它，不等于许可把站内文本整库拉走另建一个站——那仍然属于上一条「再分发」，要先问。这是一个利用业余时间维护的个人项目：没有服务等级承诺，不保证随时打得开，也不保证谜题的接受值永远不会变。四道题与那条隐藏结局的接受值在您答题那一刻会先做一次归一化（全角折成半角、去首尾空格、转小写、删掉全部空白，再把中文句号那一类收尾标点直接去掉），为的是别把答对的人赶出去；如果哪天我们把某个接受值改准、或者重排一单的流程，已经发出去的攻略就会对不上当下的游戏。这种时候改动会留下记录，错了会写明并更正——这是能承诺的两件事，别按商业服务的标准来期待第三件。
所有与这一作有关的改动都记在主站那条 更新日志 里，每一条带自己的日期、按时间倒序排。这一页故意不抄它的条数：那个数每记一条就要变一次，把「共几条」写在这儿，第二天它就成了一句假话。本页正文每次真的改动，顶部那行「最后更新」的日期会跟着走——它取自这一页正文在版本记录里最后一次被改动的日子，不是按编辑日历手写的。
对因使用本站而产生的任何直接或间接损失，本站不承担责任；本站内容用于娱乐与参考，不构成任何专业建议。游戏里出现的鲸背岛、村里的「巨兽」传说、1962 年那艘没有回来的电缆船、1978 年的那台海底泵站、守殿人的名录与从档案柜里被取走的那张保密纸，全部是虚构。它们模仿真实机构与真实档案的版式，为的是让玩家在那种界面里做出选择；它们不代表任何真实机构、真实人物或真实事件。
条款会变，改法只有这一种：更新本页，并在上方换掉那行日期。这张页上没有任何要您点的控件，浏览器里也不记录您读没读过它——上面「开始投递之前」那一节说过，标题屏根本没有勾选这一步，所以「继续使用即表示接受更新后的条款」这句话只能按字面理解：您继续用，我们就当您接受；不接受，关掉这一页就行，游戏不会因此坏掉，也不会因为您没读过条款而拦着您不玩。
条款本身有疑问，写信到 contact@gamestrategists.com；涉及个人信息的走 privacy@gamestrategists.com，以 隐私政策 那一份为准。回信都是人写的；具体多久回，本站以 联系页 上那一句为准，这一页不再抄一个数字，免得两张页面对同一个承诺写出不止一个时长。
Abyss Messenger (https://abyss-messenger.gamestrategists.com)
This subdomain holds one thing: the browser copy of Abyss Messenger: The Last Five Letters — a 3D island called Kestrel, five landmarks (the lighthouse and jetty, the southern reef, the wreck cove, the bone shrine, the deep lab), five letters that have to reach five recipients in order, four puzzles that only close once two accounts line up, twelve echo fragments you can pick up along the way, and four endings. It is published by alphaBETA DEV (GameStrategists): one person, not a company.
Two neighbouring things fall outside these terms. The pages on the main site, gamestrategists.com — the game profile, the walkthroughs, the changelog — carry their own terms; where the two disagree, this page is the one that counts for the site you are actually playing. And this game has no second distribution channel: outside the browser you cannot get it at all. Three other titles in this project (Dajin, Room 404 and Xiaoqi) do have offline Windows packages on the Microsoft Store, and this one is not among them, so there is no store-side installation, refund or content rating here for anyone else to answer for either.
Nothing in this game costs money: no sign-up, no purchases, no paid chapter, no payment method to connect. Because no money comes in, there is nothing to refund — a dispute over whether an ending was worth the walk has nothing here for anyone to act on, and no one can undo a choice for you either.
Domain and hosting do cost something, and the plan is to cover that with revenue from the Google AdSense script the pages load. The game’s own page does load one Google ad script (measured 2 November 2026: one tag on three separate samples), but the slot inside the game sits behind a switch that stops before it ever mounts, so no labelled ad frame that we placed appears on screen. Measured the same day in a real browser: on the title screen and on this page, zero boxes reading “AD”, zero ad containers with a bounding box larger than nothing. Once you are in the game the page does gain one 0×0, hidden ad container — that is the ad loader’s own standby element, invisible on screen and not a position we reserved. Which ad runs is the network’s decision; we neither see the shortlist nor pick from it. How ads choose you, and how to switch personalised advertising off, is written in the privacy policy — that is the document in charge of it. If the serving status changes, the sentence above changes with it.
One more distinction belongs here rather than in the summary: the ad script lives only in the game’s own page. On 2 November 2026 five pages were each opened three times and every outbound request was written down, and the two kinds of page do not produce the same table —
| Page | Hosts seen | Cookies |
|---|---|---|
/ (the game) | this site, pagead2.googlesyndication.com (all three rounds), static.cloudflareinsights.com (all three); googleads.g.doubleclick.net and its probe cookie appeared in one of the three rounds | one only: test_cookie@.doubleclick.net, and only in the round that got that far |
/terms (this page), /privacy, /about, /contact | two hosts: this site and static.cloudflareinsights.com. None of the ad endpoints appeared in twelve readings | none |
That Cloudflare beacon is injected by the hosting platform into every document and reports aggregate traffic and performance only. Every number quoted on this page comes from readings like these, taken page by page — not from copying another site’s legal text.
There is no “sign this before we let you in” step here: the title screen has no box to tick and no “accept” button. Measured in a real browser on 2 November 2026, the visible buttons on an untouched title screen are two — Begin delivery (which reads Continue delivery when this device already holds a run) and the language toggle in the corner. That screen also carries the way to the five explanatory pages: About, Contact, Disclaimer, Privacy and these Terms, in one row along the bottom.
Nor is there a dedicated health-warning screen, and it is honest to say so: what you see on first launch is the game. The subject matter is deep-sea horror mystery — three years ago your brother Lin Yu came to Kestrel as its courier, left five letters unposted, walked into the pump station under the reef and never came back; you are Lin Xi, finishing his last round on his route book. The soundscape is mostly low-frequency and synthesised on your own machine, and it is only created after you actually press Begin delivery: before that press this site has no audio context at all and asks you for no permissions. If you would rather walk the whole thing in silence, the button in the top-right corner turns ambience off at any point after you enter.
This is a single-player work: no other players, no chat, no request for anything that identifies you. It is not aimed at children under thirteen.
Several ordinary clauses have nothing to apply to here, so there is no rule for them: there is no account, so nobody can be banned, there is nothing to appeal and there is no one who could “terminate your service”; nothing is charged for, so there is no refund process; there are no forms that collect anything about you, no comments, no uploads and no interface for other programs to call. The game does have two input boxes — the one on the delivery check and the one on the summary screen that asks for a frequency — and each sits inside a form, but both paths stop the browser’s default behaviour first and compare strings locally: on 2 November 2026 a full pass from opening the page to entering the game, switching language and muting ambience recorded zero requests that were not GET and zero script errors on the page. Whatever you type is compared and then thrown away; it does not even reach your save file.
Our reach over any individual here is small, and, equally, only you can touch the run on your device. The five delivery statuses, the grade each one earned, and how many seconds and how far you walked are written to exactly three keys in this browser: abyss-save.v1 (progress), abyss-lang (whether the language button last left you on Chinese or English) and abyss-sound (whether ambience is on or off). There are two routes that actually work today for clearing them: Start over on the summary screen — which first reads the cost back to you in the browser’s own confirmation dialog, saying how many grades are about to go — or clearing site data for this origin in your browser. The title screen contains a second Start over button which, measured the same day, stays hidden on the page; the reason and the plan for it are both in the privacy policy, where this is written up as a defect to fix rather than a design we intend to keep. So today the summary screen is the only in-game way out.
On copyright this page keeps the wording this site has always used, adding nothing and taking nothing back: except where stated otherwise, the text, images, code, game design and story here belong to alphaBETA DEV (GameStrategists). They may not be copied, modified or redistributed without written permission. To use any of it somewhere else, write to contact@gamestrategists.com and say what you want to use it for and how you will credit it.
robots.txt allows User-agent: *, contains no Disallow line at all, additionally names nine AI and generative-research crawlers it permits (Google-Extended, GPTBot, ChatGPT-User, ClaudeBot, anthropic-ai, CCBot, Omgilibot, PerplexityBot, Applebot-Extended), and declares this site’s own sitemap. The previous version of this page said “no automated tools to scrape this site’s content in bulk (search-engine crawlers excepted)” — that sentence contradicted the robots.txt sitting on the same domain (measured 2 November 2026: Disallow 0, named allow-list 9), so it is replaced by the one above. Naming those crawlers is so that people can find this game and summaries can quote it; it is not permission to pull the text out in bulk and rebuild a site elsewhere, which is still the redistribution case above and still needs a question first.This is a project maintained in spare time: there is no service-level promise, no guarantee it is always reachable, and no guarantee that what an answer field accepts will never change. Before your input is checked, the four puzzles and the hidden ending all normalise it first (full-width folded to half-width, leading and trailing space stripped, lower-cased, whitespace removed, Chinese sentence-final punctuation dropped) so that someone who typed the right thing is not turned away; if we ever tighten an accepted value or reorder a delivery, a walkthrough published before that change will stop matching the live game. Two things are promised instead: changes leave a record, and mistakes are corrected openly rather than quietly. Do not expect a third beyond those, measured against a commercial service.
Every change to this game is filed in the main site’s changelog, each entry with its own date, newest first. This page deliberately does not copy that count: it moves each time an entry is filed, so writing “there are N entries” here would be false the next morning. When the body of this page genuinely changes, the date at the top moves with it — it is read from the last recorded change to this page’s text, not typed in from an editorial calendar.
No liability is accepted for any direct or indirect loss arising from use of this site; content here is for entertainment and reference, not professional advice. Kestrel Island, the village story of a “great beast”, the cable ship that went out in 1962 and never came back, the pump station of 1978, the caretaker roll of the shrine and the secrecy paper removed from a county cabinet are all invented. They imitate the layout of real institutions and real archives so that a player has to make choices in an interface that feels ordinary; they represent no real organisation, person or event.
The terms change in one way only: this page is updated and the date above is replaced. Nothing on this page asks you to click anything, and nothing in your browser records whether you have read it — as the section about the title screen says, there is nothing to tick before the game lets you in — so “continued use means you accept the updated terms” has to be taken literally: keep using the site and we treat that as acceptance; if you do not accept it, close the page. The game does not break for you either way, and nobody stops you playing because you never read this.
Questions about the terms go to contact@gamestrategists.com; anything about personal data goes to privacy@gamestrategists.com and is governed by the privacy policy. A human writes the replies. How long they take is stated once, on the contact page, so this page does not copy a second number for the same promise and give two pages a reason to disagree.
