Very fun game I really like it. I mean right now it's just a clone of the mining minigame from diamond and pearl. I saw you're adding upgrades and other modes and such and if you're able to implement them this game would be really fun. Even now it's a pretty good start I really like the feel of everything. The only downside in my opinion is there is no punishment or anything for being greedy and just sitting there clicking away until the cave collapses. It would be really cool if you could leave at anytime in the cave and if the cave does collapse you lose a couple of your gems. Aside from that I really like the game so far.
