I thought of an idea for an interesting thinking game. I was sitting and started thinking about gravity and outer space and thought up this: Guide a pixel into a box by using gravity centers in a vacuum. For example, a pixel might start on one end of a screen with a box on the other. The player must place four gravity pixels at different strengths on the field that, when activated, will guide the pixel to the box. It's a challenge, but it seems fun. I suppose the hardest part would be the massive amount of calculations needed which would make the game slow. The graphics are basic (a few pixels; wow), but that would make it faster. Does this idea sound feasible?
