As it is, this overhaul plays like a more annoying version of a science multiplier run, except of the bottleneck being on the research, its on the building materials, which is completely backwards imo.
Consider making recipes themselves require more steps/ingredients instead of just increasing costs. Also, the building stack sizes are just.. Very questionable, since it doesn't affect space logistics whatsoever and thus it only makes inventory managing in the earlygame a bit more annoying. Anti-QoL isn't what makes overhauls difficult, its the added complexity generally speaking.
Of course, you don't have to do any of this, just my two cents after trying the mod.
