I feel like materials and mechanics experience is gained way too slowly. I have 30 hours in this game (though some of it was idling), but I still feel like my progress through those trees are glacial. Meanwhile I have 9 unspent perks in electricity and nothing to spend them on as everything is gated behind blueprints that are annoyingly difficult to find without the heavy rover (which I have found a blueprint for, but need way too many perks in mechanics to unlock). This feels like poor balancing.
