Chaosey

What it is

Chaosey is a multiplayer co-op adventure by rizaardiyanto, played in the browser. Two to four people play together, each in charge of a single key, so the group has to coordinate to make progress. You enter a nickname, pick a server region, then create or join a room. One key per player is what makes it different from most co-op games. According to the AI game catalog GamesByAI, most of the game was made with AI; the listing comes from the Vibe Jam 2026 submission form and names Codex as the tool.

Who it's for: Friends who want to play together and enjoy the laughs that come from fumbled teamwork.

Before you start: The page opens without a login or payment prompt; the author doesn't say whether the full game is free. The catalog marks it as mobile-ready, though we didn't try it on a phone. Creating and joining rooms needs an internet connection, and your nickname is shown to others in the room; we didn't actually create a room or check how scores are stored. Menus are in English and there's no age rating.
