Cool concept. It took a while for me to get the idea and a lot of the time I was just sitting there pressing space waiting for the cube or triangle to turn to the side I wanted. Also at the one point it walked over different colors when I shouldn't be able to. That made me think, what if each square had two identifiers on it, a symbol for example, and you could walk onto a different square if it had the same color or the same symbol.
Overall good game with a lot of potential. Good Job!
