Indie demo: Bio Fail on itch.io

A playable demo for *Bio Fail* is live on itch.io, giving players an early look at a side-scrolling horror platformer built around body possession. (itch.io) The itch.io page lists *Bio Fail* as a “fast-paced side-scrolling platformer” in which players can “take control of any NPC on this level,” with each host body carrying different stats and weapons. The page was marked “Published: today” when indexed on April 16, 2026. (itch.io) A Steam page for the same game says players control “a biological anomaly” that possesses humans, solves puzzles, and fights through levels by switching bodies. Steam lists developer and publisher credits as Langonier and shows a planned release date of April 2026. (store.steampowered.com) That setup puts the demo in a familiar indie lane on itch.io, where developers often post short builds before a full commercial launch. Itch.io describes itself as a platform for creators to upload, share, and sell independent games, including free downloads and demos. (itch.io) The possession mechanic is the clearest hook in the materials now public. Both the itch.io and Steam pages say losing one body does not end a run immediately, because the player can move on and inhabit another character. (itch.io) (store.steampowered.com) Steam’s store description adds that the game is set in a secret laboratory and frames the player character as a failed experiment trying to escape. The listed feature set includes platforming, puzzles, interchangeable bodies, and a “gloomy visual style without bright colors.” (store.steampowered.com) For players deciding whether to try the demo, the current public pages point to a small-scope project with one central idea: survive by treating every nearby character as a temporary body. The Steam page is still unreleased, but the itch.io build is already downloadable. (store.steampowered.com) (itch.io)
