This is incredible feedback, and I appreciate you taking the time to give it, thank you for your words. I completely agree, and i think if i had more time for the jam I would have implemented those things! especially the upgrade or resource additions (originally there were going to be stone costs for everything as well as a mine for resources, but i just didnt have the time)!
Thank you so mch for leaving such good criticism. You rock, and I gave your game a rate too! hope your day is going well!
