"Originally Posted by alspal I think it could probably use a wider variety of hues, that single green in the foreground is a little uninteresting."
If you download the game, you'll see that there's multiple backgrounds. I'm using layers with parallax in my game. I've toned this background down a lot as it has too much contrast
I still think you should add more hue to the background, because the green is still almost the same as the foreground. Another suggestion, since the character has so much depth and detail to it, you really need to do the same to the foreground. Now you can do that several ways, but my advice is to try adding black and more detail to those objects.
