I liked this game, the two hours it took me to play it. it was slow, but it's like all mining/improvement style games I've seen, hard to start out, very slow, but if you go for the best gems that you can get to, it becomes a cake walk then you can work on getting the quest done. it went by too quick once I had my first side amount of 7,500. Make it so that you have to buy each upgrade in order to make the game last a bit longer.... also some underground hazards would be fun add on, like Water, or Lava.
