great work for a first game! really nice music, my suggestion, is: make controls more simple! specially for a gamejam when people gonna play many games and have no time for learning all the controls, you attributed many buttons, many actions, and when i read the description it made me procastinate 8 hours to play your game(yeah, i'm a pro at procastinating), maybe showing convenient contextual actions in game like zelda breath of the wild could work better. Very original idea and great work for a first game in a gamejam.
