Hello I have a few critiques. ![](http://i51.tinypic.com/htctg2.png) 1\. You should use a different color for the top of tree, probably should be darker than the grass. So it stands out in front of the grass. And the dark trunk compared to the top, doesn't go together at all 2\. Why are the cave walls so straight, it's alike bricks I think you should make it different, more like rocks.. 3\. Same as with 2nd 4\. Isn't that a little too pale? Maybe contrast it a little, not too much though so it doesn't stand out more than player sprite. That's about it, I like the game looks, but with those few fixes done I think it would look way better, hope I helped ;)
