GraviSparks

GraviSparks is a particle sandbox physics game which uses the concept of gravity as its main gameplay feature.

Create attract and repel blocks, then watch as their gravity draws in the particles! Create orbits, contain particles with negative gravity blocks and influence their paths around the screen.

This game is controlled entirely by the touch screen simply select the tool you wish to use on the toolbar and use it by drawing on the screen.

Yellow Particles
Red Attract blocks
Blue Repel blocks
Black Eraser (for blocks)
White Clear all blocks

As this game has to compute physics on a large scale, it is recommended that you have a high end device. However, when the game starts to find the processing too tough, it will try to slow down the similation rather than grind to a halt.
