I'm not quite sure what you mean by hard, but not impossible. I wasn't even trying halfway through this game and I didn't die or anything. I will say that this has a really interesting style to it. You truly have a lot of freedom with this game. I just wish I could understand how to get ahead. It helps that the title is so cool.
You probably could have put more detail into it. There's a lot of potential for this idea. It certainly is creative. I like the little sounds that go along. The menu is pretty cartoonish compared to the rest of the game.
