Fun game until I encountered a glitch. The level where there is a crack going vertically from the right, one of the enemies that turns invisible got stuck there. Since I can't kill them while they are invisible, I can't finish the level. One of my knights got stuck there too, every time I try to move him words come up over his head that say "can't move". The glitch could be fixed by allowing one of my characters to attack them while they are invisible. Otherwise a great game. Minus one half star for the glitch.
