This was a fun little game and the retro music really added to the vibe. Add some little sound effects on mining the different stones and it'll get even more satisfying! Also probably want to add some walls to the sides of the map to prevent falling out. BUT I don't know how you did it but I LOVE the dithering on the lights. Looks similar to the lighting in animal well and I could never figure out how it was done. It's a really cool effect, great stuff!
