Gravitii is a puzzle game with a simple objective. All you have to do is shoot the ball at the target. The only problem is there are planets in the way. You must use the gravitii of the planets to curve your ball and hit the target, but be careful because every planet’s gravity level is different.

Changes:

change planets so that they are darker the more dense they are.
added extra ingame controls
added a screen when the game is completed
