Attached is a prototype of a physics game I invented while playing the built-in port of Box2D in the Love2D game engine. There are a couple versions: the older one, where you can push blocks around by adding new block but you don't know what color you're going to add, and the newer one, where you know what color you're going to place next but you can only add blocks to the bottom of the screen. I'm still experimenting with ideas so STAY TUNED. :I
TL;DR: 2 versions of my game prototype, click to place pretty colored blocks! Yay!
