Arrow key are to move in a curtain direction, gravibox wont ever stop moving be careful.Dark red moves you up brown moves you down, green is the finish of the level, you can only change direction when gravibox is touching the yellow, blue/edge kills you.
There are more levels coming soon, there arent that many, because i had to rush it. insiration taken from the game called Gravity 2, the song is also by the same person who made Gravity 2. Enjoy
