I understand your struggle with finishing the game, the theme was pretty prone to overscoping :D
The first thing that came to my mind was making a Spore like game before I was reminded of the amount of time we would have to actually finish it.
But the assets you've made are amazing! I love the atmosphere. No doubt it would've turned out great if you had more time. I suggest you work on it after the jam, it has a pretty neat idea behind it.
