Make so you need to actually add more drills inside to be able to mine more area. As of now, it's quite cheesy. Maybe also require lubricant/drilling fluid to mine?

Make it require more power compared to normal? 150%?

well it is a cheat mod after all, also the power consumption already scales so its not like you're getting power for free, its just convenience.

could alwways add a few options to make it more expensive or give it some more drawbacks to make it a bit less cheaty for the people that care about that

im open to some reasonable suggestions

Not sure if it's possible, but maybe make it consume the drills to allow higher OC up to the limit of the planet?

consuming extra items is not something i can easily implement
