Gravity Flipper

Flip the gravity.

My first game. I made the scripts, textures and sounds by myself. The game is about Ball, it can fly forward by reversing the gravity. Help it collect coins and avoid obstacles. This game is hard, sometimes even impossible, because I'm not an expert in making games, so rely on your luck. It's similar to Flappy Bird, but instead of jumping in the air, Ball flips the gravity.
