@Kuupu: yes, this is because there are 3 maps. Post-LD there will be a proper menu, plus map editor. Also, some mechanisms and enemies are to be done later on.
Love the music and the graphics style. But the game is lacking a challenge and a goal so far. But since you're still working on it, I hope to see more soon =D
I can run it with the command 'love .' though.
I think it might not be packaged correctly?
The graphics are really pleasing, and the movement is well done (the little "skipping" animation)!
