Really good game. The spawnrate upgrade ends up being a huge nerf after prestige 2 though, nearly couldn't complete pres 2 at 360 but easily beat pres 3 with no spawnrate upgrades
Hi! Yes, I've been thinking about adding the possibility of disabling upgrades or downgrading so the player can strategically select if they want to mine resources for money or mine rocks for upgrades or they're just making a run for the cave. I'm adding it to the backlog.
Thanks for playing and for your feedback!!
