Well. I like the game a lot. Really addictive, and the music matches the theme so perfectly.
Some things that you can possibly improve:
1) Ability to jump higher as a big guy. I got so big that I couldn't jump higher than my toe nail.
2) Add tools to be found to get rid of (some of) the stones blocking the way.
3) Level system with increasing difficulty / set a goal to achieve so one can actually finish it.
4) Ability to print the maze to put it on the wall.
