That's strange... Do you have the Zero Engine program? From what I've experienced it only works if you're on a computer that has the Zero Engine program downloaded on it. Try getting Zero Engine and then try playing it again. Then reply and tell me if it works, ok?
Actually I just noticed that the license agreement window had opened behind the browser window and I didn't notice the icon, my bad. It's a simple, but relatively nice platformer, the movement is nicely fluid for a game with this theme. Some jumps are a bit frustrating when they're so high and it seemed that your jump height varies, so you can't always get the tallest jump.
