Really great game and love the art style! I also enjoyed your use of the limitation, getting smaller as you use your own body as ammo seems to have been a popular choice in this game jam but you're the first game I've found to make it so if you don't use ammo at all your body gets too big and you also lose. Forcing the player to keep the delicate balance of having to keep using ammo to live but not use too much or you die keeps the game fast paced and engaging.
