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?
