feedback
good: i like the concept of the game, it's pretty original and i like the sound design, it works well with the game,
bad: i'm not a fan of the pixel art, although i can tell what the sprites are which is a good thing, some of them seem a little unpolished.
bug report:
after the first go of mining it auto kicks you out even if you don't click anything. i'd say its inbetween a class C and a class B.
overall a decent game :)
