Dig it! Esp for 2 days effort! It's nice and simple and fun. Kept my ADHD brain occupied (with an autoclicker) happily for 15 minutes \o/
But if you are gonna lock me into a skinner box type mechanic for a few mins, let me turn the sound off xD or have a little more of a softer mining sound omggggg (even without the autoclick it was grating! .... unless that is what you were going for, in which case, nice! :D )
But, was in, was fun, mined the things, upgraded the things, mined more things, won the game, got out, didn't take too long. Actually a pretty damn lovely little experience I think ^ _ ^
