Thanks for playing and the feedback. The chopping is strongest when the bar is full, could definitely do with some clearing up. The UI is pretty buggy too, Its still basically just some buttons thrown together on a background lol.
As for the mine minigame, my intention was to have no way to go up, forcing you to dig down or sideways. The amount of boulders, lava, and gold all increase as you go lower, so it's a tradeoff between staying at the same level with less reward, or increasing danger for more reward, but with no going back! I intend to put in upgrades for the mine, such as explsoives to clear boulders, so hopefully it'll end up more rewarding the more times you do it.
Thanks again!
