I like the idea, I truly do.
But the game itself isn't that good.
It's way better than I can do, so don't take it as an insult!
First of all, it's very slow.
Slow game, and slow to react to the controls.
The character never is on the same level as the ground. First he was floating above ground, then after half the level, he was beneath it to his ankles.
And the music stopped a bit in, and didn't come back.
These are some of the things I think you should have a look at.
But as I said, this is helpful critism, and not complaints! I'll stay tuned.
