Sound will definitely be added, but I only got my game engine to the minimal viable product in terms of making any sort of game in it.
The engine was also lacking animations and sprite sheets during the jam, hence the absence of any movement from the characters... so I just leaned into it looking more symbol based.
It definitely wasn't a game I ever imagined I would make, but I am interested to see where I can take it. I like the idea of not directly controlling the character but it responding to your actions in a deterministic manner. I've made a few tweaks (and created a new food type and level) since the jam based on some of the feedback I received and it improved the playability significantly.
