This is a great game!
The only compliant I have is that the buttons were poorly placed. I don't usually like it when you can't use the arrow keys instead of WASD and using the shift key to help jump late in the game was very awkward, especially when tying to change colors. However, that aside, this game was awesome. The time on my stats screen currently says 315 minutes! (And that's with few interuptions.) Any game that can hold my attention 5 and quarter hours is worthy of nothing but the utmost praise. Well done!
