Nice game, in a way this feels like an incrmental game that isnt based on mouse clicking but rather on platforming and movement.
I love the concept, I am looking forward to an expansion of the whole thing!
would be great if the "auto miner" aka mill and co. would actually increase the money in real time, without the need to go and take it (but also might be okay as it is)
cocnerning "prestige" I could think of some armor that you could buy. When prestiging, a storm or soemthing might crush your mills and stuff, but you obviously keep that super expensive armor you boght since it is on your body and therefor wont be destroyed.
by basically stuff stored in your inventory/on your body you could have stuff that is kept even after prestiging. basicall creating "permannent upgrades" vs the temporary upgrades like the mill that die upon prestiging.
obviously also have some multiplier items that increase how much money you get from automine and from manual mining :-)
so yeah, basically converting your usual mouse idle clicker game into a platformer based thing.
I love the concept, looking forward where this whole topic is going! :-)
