Can't say I like the level style, specifically this:
and when I say specifically, I mean the grass above the cliffing. It looks horrible, stick with the default layout for cliffing.
Also, the HUD layout is pretty bad in my opinion. Why are the ASDF keys in the same corner as the health? Having it shoved all in one corner, and especially have the ASDF offset from the side is pretty bad. Try to keep the HUD balanced visually. Also, buff up the margin some. I hate when the HUD is shoved right along the edge of the screen.
