This is a pretty cool idea, and the graphics are great! However...I'm not sure how playable it is, actually. Just that level with the platforms over the spikes, it's really difficult! How about something like... in one 'world' there are spikes, in the other you just jump for no reasons...There have been games that have done this concept and done it well, so maybe if you work on it it'll become something really cool. Because honestly as it is, I just can't get very far...
