About 细胞防线
A casual roguelite tower-defense game for mobile on TapTap. It simulates the human immune system: bacteria, viruses and other pathogens attack, and you place different kinds of immune cells to protect the heart at the centre of the screen. Each pathogen has its own traits, so the defence has to change with the attacker. Between fights you level up skills and buy items with in-game currency; battles come in easy, normal, hard and endless modes, and level-ups offer a pick of three random upgrades. The developer, who goes by 难以离开, says on the store page that it is a one-person project, that most of the code was generated with the AI tool ChatGPT and that the art was made with Midjourney; the idea came from sleepless nights after catching COVID at the end of 2022. The games site 罗斯基 covered it in May 2023 as an AI-made TapTap game and relays the developer's account of building it in Unity in about 60 hours. Free on TapTap for Android and iOS; released on 6 Apr 2023 and still updated (version 7.7, 1 Sep 2026), although the page now labels it a test version with a trial button.

How it was built
Partially verifiedThe game description on the TapTap page says most of the game's code was generated with the AI tool ChatGPT and the art with Midjourney ("本游戏的代码大部分使用Ai工具chatgpt生成，美术使用Ai工具midjoureny"), and the creator note signed 难以离开 says most of the code and art came from AI generation. In the developer's video as relayed by 罗斯基, the core combat code was generated entirely with ChatGPT: the developer asked for basic tower-defense code and then added constraints one at a time (movable towers, pathogens attacking the heart, a health limit, tower types, pathogen effects), asking again whenever the code would not run in Unity. Other modules were generated the same way, and the developer wrote some simple ones by hand. ChatGPT was also used to weigh design options, such as fixed versus movable towers, but the developer says designing the game entirely with ChatGPT was not workable. No model version is named and no code share is given.

One-person project made in Unity, according to the developer's video as summarised by 罗斯基. The developer prompted ChatGPT for basic tower-defense code, added rules step by step and fixed what would not run in Unity by asking again; ChatGPT also served as a sounding board for design choices. All images were generated with Midjourney. The game has since been updated many times (version 7.7 in September 2026).

“本游戏的代码大部分使用Ai工具chatgpt生成，美术使用Ai工具midjoureny”Verification notes: The AI claims come from the developer's own text on the TapTap page (the game description and the creator note signed 难以离开) and from 罗斯基's May 2023 summary of a video by the developer, which we did not watch. Both say most of the code, not all of it, came from ChatGPT; the article says the developer wrote some simple modules. Solo: the description says the game was developed by one person. Launch date (6 Apr 2023, 10:00 China time in the page data), version 7.7 (updated 1 Sep 2026), Simplified Chinese, Android and iOS, price 0, developer account 烛光工作室 (supplier xuepeng), rating and followers from the TapTap page on 4 Nov 2026. Engine and the 60-hour build time come only from the article. The article's headline and the developer's video say the game passed 10,000 downloads within three days on TapTap; this is the developer's claim and is not recorded as a metric. The page's 热度 (heat) figure of 45 万, which TapTap's structured data marks as a download count (456,326), is not recorded because it is not confirmed to be downloads. The article also says the game made money from ads in 2023; no revenue figure is given. The page now carries a test label and a trial button despite the 2023 launch date (see conflicts).
