Fun and addictive game, well done! Small criticism, in that I'm not sure how it fits in with the theme.
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!
