This is a very strange game. It's not so much that it's hard, it's just that it's complicated. It's weird to have all these different ways of attacking your enemies. There really are a lot of weird combinations, but so few of them work. I at least have to give you credit for having some creative graphics and characters. For some reason, it waited awhile for me to lose a level.
Level 6 is the one where I'm really having trouble. I have to put everything in the right order. You are truly limited with what can be used to destroyed what here. Well, there's always the walkthrough. It's probably worth checking out.
