It's really easy to flip up-side down in this game. There isn't a clear, indicated way to restart or re-flip, so I decided I'd fly into the sky. Weight isn't programmed into the game, so I just flew around for a bit until I got bored. You can fly way up high, until you see the design of the level. It's a decent track, but it has many twists and turns, so flipping is inevitable.
