Ahh, I think this game has so much potential if only you had the opportunity to put more explanation on what is going on. Please consider putting some extra information on the game's page. If it is more clear what you have to do and why that would make this so much more enjoyable.
I think the graphics and gameplay and also music are very well done in general. I agree with others that the graphics doing necessarily guide the eye to what is important very well. Maybe a bit less contrast on the less imprtant pieces but other than that a very good experience. If only I understood the point and mechanics of the game better!
