Pretty cool game, I enjoy the pixel art and the chip tune music. 

Is there other attacks than your standard wand attack? I felt I was running out of mana too quickly and they enemies overwhelmed me. Some kind of melee or AoE attack would be great there.

Great game though, easy to play, but I'd love to have more attacks. And I like the idea that your own minions have turned on you, oops! That's what you get for playing with the powers of darkness.

Please, can you upload the game to try it out?
