Thank you so much for the detailled suggestions, i really appreciate this. I find both your points very clear und sensible.
The first point should be improved in the demo for the full version, where you only unlock the resource-related upgrades after retrieving a resources of that type.
The second point is also really good, something i need to think about a bit more. Both your solutions would work and have their own merit. Both should be playtested at some point, implementation is usually quick :)
I regularly post updates on our discord, and discuss suggestions from the community. Please join if you like! Maybe i'll also start a video devlog, but on the other hand i need to make sure i spend enough time actually working on the game :D
