I'm glad you liked the game! Unfortunately I ran out of time and couldn't add much content. The peasant upgrades increase the amount of resources they generate per second, but the system is buggy. My original vision for the game was much bigger, but I underestimated how long the nodes would take to get working right. I'm currently rebuilding the system from scratch with what I learned to have a more stable foundation to add content. Thank you very much for the feedback!
