The graphics are great, clearly the strong point. Unfortunately I didn't quite understand the concept. It was only when I played a second time that I saw that wheat could feed humans and what the point of feeding houses was. I thought I understood that feeding humans makes them evolve and makes them more resistant. There should be a small counter of the number of seconds of survival to quantify the challenge. Maybe a little ambitious for a game jam but this is precisely the opportunity to test things. Good work!
