Bio Fail Demo

About this game

You are a mistake. An experiment that didn’t go according to plan. A biological failure.

In a secret laboratory where experiments were conducted on the edge of life and death, something emerged. You are a parasitic monster without a fixed form. Your only ability: to possess humans and use their bodies as weapons, tools, and expendable resources.

Bio Fail is a dynamic side-scrolling platformer set in a dark world. No heroes in shining armor. Just you, your victims, and your thirst to escape.

✅ Possess any NPC on the level

✅ Losing a body ≠ death—you simply search for a new victim

✅ Every person has a unique set of stats and weapons

✅ Switch bodies at any time

✅ Platforming + puzzles through choosing the right body

✅ Gloomy visual style without bright colors
