[SKELTON S. SKELETON]

The ground tiles seem less like they're effective at conveying ground, and more effective at conveying a bunch of random, brown noise. The way they also drop off into a brown void is very unpleasant. Take a look at ground tiles from other platformers, too. Not only do they usually avoid having an entire level comprised of the same ground, they keep up a level of "detail" all the way to the border of the screen.

Here, look at the tiles from the center of this stage

They have a simple, repeated pattern to them but because the pattern isn't entirely horizontal they don't become too repetitious, they look good and i'd wager saved a lot of space for the developers.
As a whole, noise seems to be the entire problem with this style.
