I see a good looking and playing game, but with a very bleak appearance. Sonic games normally have much brighter colors all around, typically more in the foreground than the background. It also looks like there's a moderate blur covering the screen at all times, as if vaseline was smeared onto it. Despite my criticisms, it seems like you're putting a lot of heart and soul into this project and it's looking very nice so far. I say keep up the good work.
