Looks like I can walk out of the world.  I liked the random generation but it needed a little bit of cleverness added to it, got into many situations where enemies would spawn on me or bunch and make it very hard to do anything.  I am not a fan of the spiral attack, made the game much harder, I wanted to be able to swap my spells, maybe with right mouse?  Still, great artwork and I had fun.

Really cool art! I don't see how it fits the limitation though.

Well, you fooled me thinking the new wands were power-ups :D

Also, there's a level where you can exit the level from the botton and you exit the play zone. Is that intended or is it a bug?
