This game has potential, however there a quite a few things that I didn't enjoy which I will try to express as constructive criticism.
Please remove the level that you go to if you die, or if you need to keep it, please make it brighter, I don't know if it was just me, but I had a really hard time seeing the level, and at the end before the goal I really did not like the fact that there a was a roof stopping me on that final jump. The story's alright, and to give you credit there were no bugs I found, so while it was a clean game, I think it could use some work. Good work and good luck on the next one!
