This game is not bad. I like how the scene was drawn. The story plot seems potential. However, there are some things you should fix:
1) If you finish a map, there is a chance you can be stuck in it, or else the walls are not moving.
2) Sometimes you almost get a new map but if you press jump again (jump twice), that will cause a bug like I have said.
3) Saving mode should be added.
4) The acceleration is quite small, which makes the player really difficult to move.
Overall, keep up this work =)
