Well, I was going to call this a great game, but it did have an annoying flaw. You had to reopen the chests! I don't want to have to do that every time! It can be hard determining what can kill you. You usually always learn the hard way. That's a pain in the butt.
Still, it's a nice setup. I don't know what these enemies are. They remind me of some from Mario. I don't know what the "J" and "Z" did. You know, when the screen changed.
