Pretty fun concept for a platformer, although it's a bit confusing. I think it would serve the game well to make it a bit more clear exactly how these sodas work, and what the differences between the different types of sodas are.
I'm ambivalent about the graphics. On the one hand it's a really unique style that gives the game an interesting feel. On the other hand it hurts my eyes and my brain. So I guess I'll come down somewhere in the middle on that one.
