Fun game I got hooked so fast lol.
I want to point out a few bugs though.
1. when the time ran out and the buttons to go to the next area appears, I could still mine treasures in the background.
2.when I ran out of picks and the screen to buy more picks or go to main menu appears if I have no money and click the buy picks button i still get to mine treasures all the way through.
and also I couldn't figure out how to use tests and what they do. is this a feature you did not have enough time to implement or something? or am i completely missing something here lol.
