Nice! Seems like it has a lot of replayability. I am terrible at platformers, so I'm a bad person to review this type of game. I didn't make it through the first level, let's put it that way XD
The introductory text was quite extensive, and I think could do with being pared down to get into the game a little quicker. I also found the custom font a bit hard to read at times.
However, there was a real feeling of "just one more try!" which I think is a good sign. Awesome submission, well done :)
