Thanks for playing! I'm happy to hear that you liked the art.
The reason for such small worlds is that I didn't add any sort of chunking so I didn't want to risk too many blocks at once causing slowdowns on some people's computers.
And empty worlds is a bug, of course!
Do you have any suggestions, aside from fixing those two things?
I can't really think of too many other suggestions. What's currently there seems polished enough to me as is.
Visually you could probably add quite a bit, a couple of grasses and ferns here and there, clouds on multiple layers, ...
The layered backgrounds give the worlds great a sense of vastness that I think you can exploit further if you wanted to.
