This is lovely. It could indeed use some more instructions, but I suppose we all managed to get there in the end, so it doesn't need them. I quite liked the little discoveries I made. :)
It's a bit buggy. You don't get hurt if you push the enemy (but you can push them off the screen, so you can't finish the level). Needs a lot of work to receive more than two stars.
I'll work on that. I'll try to fix the bugs and add some more levels so more people will enjoy it. Thanks for the comment anyway as it can help me develop my game.
edit: added it already, hope the game is more pleasant to play now.
