I will add a photosensitive seizure warning probably on itch.io page, and the bounciness in the third level was on purpose to make the game a little bit challenging.
I've gotta ask - was this supposed to be a rage game? In the description, you have "Puzzle game", but I don't see, how this is a puzzle game, because there are no puzzles.
Well for me the game was harder than I expected and when I saw the bounciness, I barely got to another level. Maybe making the game a little bit easier will make more players finishing the game and seeing the exit.
