I dig it! (hyuk hyuk) All-around solid mechanics, UI, graphics, gameplay loop, etc. Felt like it had a good sense of progression, both in terms of gameplay loop and how it teaches the user mechanics. Also felt like it wasn't just an idler; had some fun and active ways to play and optimize further with user input. Only feedback complaint I had was maybe it show how damaged a patch of dirt you're digging at is (like how minecraft blocks get cracked progressively), but that's a small thing against everything else working well.
Oh, and 247590!
