I think my favorite part is the filter. It makes things in the distance seem dream-like and surreal. That's a very powerful thing.

I don't think the desert? level is working or it's rendered weird. The preview image is like a red desert but it comes out completely black, see pics below.

I think some basic interactions would go a long way in your game. Don't need many, they don't even have to be purposeful. It could be something as simple as clicking on a box and watching it change color. Just something that keeps the player looking for stuff to mess with.
