Really nice graphics. The gameplay is simple, but I appreciate the dynamic you are creating.
The first time I played it, I was not drawn in enough. I didn't play long enough to feel like anything was "scarce". After reading the game's description I realized that there was a further mechanic; that of scarcity. When I played a second time, I resolved to play without eating humans until I felt compelled to do so by scarcity. That was much more interesting, because of course I was eventually eating primarily humans.
So my comment for future improvement would be:
- there should perhaps be something compelling me to want to continue playing, like a high-score or something that I am growing/building (a tech tree, a family, a garden: anything permanent). Maybe evolutions or customizations?
- there should be some initial barrier to prevent me from eating humans. Right now, eating humans is about as hard as eating fruit, so the transition doesn't feel scary. My first game I ate fruit, and then humans, without really noticing the difference. If lower health affected my ability to move, or jump, or just slowed me down somehow, that might be enough to encourage me to eat fruit as long as possible.
With that stuff, and the stealth and human encroachment that you mentioned, I feel this would be a very compelling experience.
I rate this game pretty highly, and I hope you go forward with it post jam.
