dont know if its intentional but "gold/ore level" & "fortune/Ore level" seem to be really strong. Two things to add maybe: an option to buy multiple upgrades at once & hovering skills in the tree could be easier. Otherwise fun game, great work!
No, it’s not intentional. I haven’t fully worked on the balancing yet. Since it’s a prototype, it will still evolve, so doing proper balancing now wouldn’t be very effective. And thank you for the feedback, it’s very encouraging!
