The installation is what scared most people away from playing your game I think. So next time use web or just a zip.
Now the game:
It's hard, one mistake and you are back from the start, it's really frustrating, also the movement are floaty and not tight. The thing I liked are the graphics using simple shapes but good color scheme, I like the tutorial text a lot, very smooth (but it stopped being good after seeing it for the 7th time)
Overall, nice game but need lots of improvement :)
