Cool game that you created. I loved how intricate and detailed it is, but at the same time it was very complicated and hard to understand, so if you want to ensure that player navigation is smooth, add a tutorial or help section. Second, try to explain things with iconography. What am I upgrading? Am I turning winter into spring? So many unanswered questions I had while playing the game. Hence, I think explaining things rather than leaving users guessing would've been beneficial, maybe even adding it to your game's description. However, it's a solid game, and I would love to see more updates on it after the jam! Keep it up!
