This was really fun. Right before this little hole on the second level, my macbook started running a bit slow and the collision detection somehow sucked the marble into the floor.

Physics collision bugs are more likely to occur during frame rate drops. We’ve tried to address this by implementing an auto-respawn mechanism to handle cases where the ball gets stuck inside a collider, but it seems this sometimes fails. Anyway, thank you for playing!
