Thank you very much! Maybe you're right about theme, only Mark (or people) can tell! I see a connection between Bub and food: he can't stay too long without it, he can't stay with too much food in belly.
However, Gmtkjam's themes are so loose: in my opinion this game can fit well also in 2020’s theme (Out of Control: auto-jump, no control about Bub's weight), 2019’s theme: (Only one: food is the only one kind of obstacle), 2018's theme (Genre without Mechanic: platform without enemies), 2017's theme: (Dual Purpose Design: every bonus is a malus too).
I'm looking forward for your entry, now i'm working on another one!
