the upside down section seems to be bugged, I think your colliders are too small and the ball's rolling out of the 'reverse gravity' areas
I'm curious if it was a bug or I just didn't make the game mechanic clear enough. The reverse gravity is actually a timed powerup, I believe I made it something like 10-15 seconds for that section so you have to race to the end. The ball starts glowing when you get the powerup and will start blinking faster and faster until the time is up. My friend was playing the game and didn't realize it was timed either so I think I just didn't make it intuitive enough unfortunately. After hearing that, do you still think there was a bug? (I'm taking notes hehehe)
