God, I adored the art and music in this. The pixel art of the various mechs are so wonderful, and I'm a sucker for the pieces that accompany you digging through the world. Just a deeply relaxing game to me. I would have liked a bit more feedback while digging, personally; like, noises of going through the dirt and rock and stuff, very minecraft-y sound design, but that's a minor nitpick when the rest of this looks and feels as good as it does.
I literally can not hype up the art of this enough. Amazing job, everyone involved!
