I like the idea of balancing all 3 needs while reflecting on being a rat, but the platforming kinda ruined it for me; I spent more time trying to jump into the higher area rather than eating, sleeping or exercising.
As others mentioned, the turning around is super sluggish, but I also think the rat's hitbox is bigger than it needs to be and the momentum isn't quite right.
The platforming aside, the game is great at creating and mantaining a mood; the music, graphics and (if the platforming worked) gameplay all create this weird mood that I strangely like. Making everything fit together to make a mood as cohesive as this one isn't an easy task, and this does it masterfully. The only part where it really stumbles is in that platforming, where it kinda breaks the entire thing.
But hey - you got one of the hardest parts of making a game really well-done; that's something to be proud of, even if the end result didn't quite come together like expected.
