I think that both the unlimited belts and unlimited mining mods arent too well balanced as to get a tier 5 drill its only just 5 times the vanilla's cost. and for a drill that can mine at 3 per second with 18x18 range is incredibly cheap. i have an idea on how to make things more balanced (at least in my opinion) to add some extra parameters in the settings like at what point would the tiers require this science and being able to adjust how much science you need to research something. though you dont have to implement any of this, this is my idea to make the mod more balanced. and im just giving some feedback, i like the idea of the mod just the costs of everything seem a bit low.
