It looks like you're quite experienced in the aesthetic part, the game looks awesome for the time given. We just spammed on any button that lit up though till we reached space so the gameplay part was more of watching how the world transforms than actually playing. Maybe adding the specific cost for upgrades (instead of just -food for example) or some "population limit" or "build limit" mechanic would improve the gameplay as well! Overall great addition to the jam. When you are able, we'd love to hear some feedback on our game as well!
