The art is beautiful and having a 2D game around a round world is very cool, I don't recall playing anything that's done that (at least not with the ability to mine it). I could see this being very cool if you wanted to keep developing it!
We're definitely gonna keep developing it in the (hopefully near) future! If you really like the art, give @Rainwad a follow — or me as I'm gonna rope her into more game jams since she roped me into this one!
