Gravity Box is a minimalist skill-based physics puzzle where you use blasts to push a box around hopefully in the finish point.
The early levels will teach you how to play the game and present the basic concepts you are equipped with a rocket launcher used by tapping on the screen. Blasts are created where the rocket explodes.
The game's difficulty consists in using the right amount of force by launching rockets at the right distance and angle.
It's time to remember the laws of motion!
