This is a 3D game being drawn as a 2D top-down view. Some parallax confusion is unavoidable. I didn't write a more advanced lighting engine just because it was cool- it helps to identify the edges of things but there are still cases where confusion will occur.
I might be able to at least make it so it won't place a tree where it would create more parallax confusion for when the world is generated.
The grass is too vibrant. Makes it basically impossible to see most of the HUD and really hard to see the sprites.
Hrm, I take a think about that (I'm not seeing it, but I will probably adjust the tone of the grass anyways).
