Crude humour and sexual jokes on the game's own pages: the itch.io page lists “marry hot anime girls”, “get ligma” and “piss on your enemies” among its features and is tagged survival horror; the official site adds more profanity and sexual jokes. (itch.io)

About BLISTER ONLINE
BLISTER ONLINE is a free online role-playing game with a weirdcore, liminal and survival-horror look, playable in the browser or through a Windows launcher. Its page describes a persistent online world that keeps growing: over 53 biomes, more than 900 monsters, over 50 bosses and more than 2,000 items, with guns, swords, magic and summons, skills to level, quests, a city to build and planets to visit, plus bunnyhopping and surfing like in the Source engine. The world is meant to be strange and hostile, with the player small and weak at first, and to reward curiosity over instructions. The tone is deliberately crude, with jokes about marrying anime girls and urinating on enemies on the game's own pages. The developer, 22blister (u/swingking_x on Reddit), wrote in September 2026 that the game had 14,000 lines of code, all written by AI across 1,500 versions. The itch.io page says an AI keeps developing the game from the developer's input and ideas from the community but never comes up with content on its own: everything is written, specced and approved by the developer before it goes in, and players are invited to comment with what they want added. In English.
How it was built
Partially verifiedIn a post on r/WebGames (7 Sep 2026, UTC) the developer writes that the game has “14k lines of code, all written by ai across 1500 versions and anyone can add their prompt to it.” The itch.io page says: “the ai keeps developing my game forever, using my own input and ideas from the community, the AI is working on this game constantly, but never coming up with content on its own -> everything is written, specced and approved by me beforehand before it gets into the game”. Players' ideas reach the game through the developer, who decides what goes in; neither source describes anything generated while the game is played. The AI tool is not named.
- Developeritch.io page, “Why AI?”: the AI develops the game from the developer's specs and community ideas, and everything is approved by the developer first. AI disclosure: AI Assisted, with Code, Graphics, Sounds and Text. — itch.io
Per the developer, an unnamed AI tool writes all of the code and keeps extending the game, version after version (about 1,500 versions and 14,000 lines by September 2026), from features the developer writes and approves, many of them suggested by players in the comments. The game runs on the developer's own server, with a browser client at play.blisteronline.com and a Windows launcher.

“14k lines of code, all written by ai across 1500 versions and anyone can add their prompt to it.”Verification notes: AI use and the code figures from the developer's post on r/WebGames by u/swingking_x (7 Sep 2026, 12:04 UTC), read from the Arctic Shift Reddit archive; features, the “Why AI?” statement, status (Released), platforms (HTML5, Windows), genre and AI disclosure from the itch.io page, and the content list from the official site blisteronline.com, all re-read on 5 Nov 2026. The line and version counts are as of the post. The Reddit account and the itch.io account 22blister are tied only by the post linking the page in the first person. “Anyone can add their prompt” describes how players' suggestions feed the developer's AI workflow; the page says the developer approves every change, and nothing is described as generated during play. The browser launcher at play.blisteronline.com was checked on 5 Nov 2026 and makes no calls to AI services; the game client it opens (play.blisteronline.com/game.html) was also checked on 5 Nov 2026 and contains no calls to AI services. The Windows launcher was not inspected. The itch.io page shows no publication date, so the release date is not recorded; the developer had been working on the game for “the past few months” by 7 Sep 2026. Content figures (biomes, monsters, bosses, items) are the developer's own claims. Team size and location are not stated. itch.io shows no rating or download count. The game was not played.
