Nice gameplay, I personally like short paced gameplay (only my preference), it would make a good mobile game. I understand a bot is supposed to be bought to make mining alot easier. Would be awesome too if I could pay the developer so that I can skip mining for some items. I managed to play for 30+ minutes, its comforting to some degree, but I couldnt hold up until the last empty box that required 20 metal items. Nice.
