About the game
Bulbo's Belief System is a puzzle-platformer where knowledge is both a tool and an obstacle. Bulbo believes everything he's told, letting him see, move, and interact, but he can forget! Erase walls from existence, ignore gravity and manage conflicting beliefs to solve cute mind-bending challenges.
Original Steam description
Bulbo's Belief System is a puzzle-platformer where knowledge is both a tool and an obstacle. Bulbo believes everything he's told—learning allows him to see, move, and interact, but forgetting is just as important.
Erase walls from existence, ignore gravity to walk across gaps, and manage conflicting beliefs to solve mind-bending challenges. Experiment with what Bulbo knows (or doesn't) to navigate a world where perception shapes reality.
Can you control what Bulbo learns and unlearns to reach the goal?

By just listening to other characters, Bulbo learns!
Bulbo ignoring the concept of gravity

Bulbo forgetting a wall
if you don't believe in the wall it can't stop you!
