I like the core concept a lot and think it fits the theme very well. Reminds me of Kirby games and always loved those.
I wish it was possible to heal by eating the dead guys. Then maybe I'd be forced to experiment with other abilities now and then instead of sticking with my favorite/safest option.
All in all fun idea, would be excited to see it expanded upon! Good job for implementing it as fast as this jam's deadline :)
