It's great especially for a jam game! I love the concept, and I love that I was actually able to play it on mobile thanks to the on-screen controls. You should make the 'b' button exit out of menus so that you can lean into this.
My biggest gripes all just come down to stuff you wouldn't have had time to implement -- not being able to use items directly from the inventories, when you use an item from your bag it puts you back at the top of your bag again, not being able to save, not being able to use your flash light indoors... I wasn't too keen on being a racoon, it kinda took away from the zombie survival fantasy.
What I liked was being able to wiggle around the control stick, being able to level up so fighting zombies isn't all bad, being able to find books to raise your stats was a fun way to incentivise gathering, and I liked the creative way of using the Gameboy LEDs for Hunger/ Sleep need. Although I was left wondering if I over-ate would I be wasting it or not?
Anyway I think you could very easily keep expanding on this and be successful. I reckon you could do great by regularly updating when you add small things instead of trying to go away and do loads at once because you already have a good base. I think you should change the cover art to be more clear about the zombie aspect eg. show running away from a group of zombies as if you want players you gotta give them more of an idea of what they'll be doing in the game.
Anyway, lots of potential! Good luck!
