4.5 because I love the game it's fun but if I am doing something I get a ad then when I get back from the ad 2 seconds later I get another ad. After the ads everything is all laggy and also for me it's hard to control the guy. Very fun game. My progress saved. I haven't gotten too 1000. Oh wow I like the update it has gold in the mines now and diamonds! Works pretty well, but could you add more variety to this? Like layers in the mines, I'm at around a depth of 100 and nothing has changed. Just more dirt. (If there are already layers, please let me know where they start at!
