Nice game, I only noticed one small mistake. ( screenshot) The game is time-consuming, sometimes you have to wait a long time to do something, but that’s the point, so I rate it 9/10.
I understand your issue, my brother also has that issue
I will try to make pickaxes deal more damage or blocks at lower health, but I don’t want to make the game too fast or it would be boring, so what I am hoping is to get a better rebirth formula and get better health/damage system
