Cute game! I liked that the levels wrapped around horizontally and vertically - it made for some interesting compact levels. I liked how you had had to use enemies+shield to allow you to diverge from the straightest path to the end and grab the gems - it gave the game depth and an element of strategy. I'm still not 100% sure how the shield functioned - I think it allowed me to be pushed back by the enemies? But then sometimes I would trade places with them.
