Change, ah change, another of my mostly finished games. In fact, it may be my only finshed game.
Its super simple, while being super hard to learn. (this may be its down fall) Solving inner puzzles gives you colors to conclude the outer puzzles which give you time and points. Score as manny points as you can in the time provided.

I am planning on selling this one too, but again as with union, if it all goes tits up, which it will. I will realeas them for free.
