I quite liked this game. It's pretty fun, but I have one complaint. Why is the final boss so retardedly difficult? The armor boost upgrade makes this fight almost impossible. And any small hit makes you go off, and if you already double jumped, you're pretty much screwed. Maybe next time, make it so you just take a bit of heaalth when you fall instead of dying.
It wasn't bad. I have to agree that if you want the player think, try to make your point more subtle. Bashing your ideas into my head just made me want to skip all the dialogue after the wizard.
