A gorgeous submission for 72 hours work.
It looks pretty well polished aesthetically, and could make a great series/ larger game.
The only problem as several have said is the controls. Movement is so constrained, and there is no feeling of carrying on momentum when you jump. That being said, left-right movement feels good, and idle floating animations for the food is a great little touch that really added to the overall look.
I don't even know if this has a backstory, and haven't checked if there was a theme for the NGGJ, but fuck it. It's just pretty fun to play
