This was great to see as a submission at the game jam. The day-night cycle was a fun implementation, although you maybe should consider shortening the night cycle in some way (or find something that tempts and encourages players to move during the night).
I remember playtesting one of the earlier prototypes, and would have liked the shoving physics put back into the current version. For some reason it felt a lot more funnier to accidentally push the other player away or find yourselves trying to cooperate but failing miserably. Perhaps you can look into making even more exaggerated moves or special moves that these characters could do.
Overall a visually-pleasing addition to the gamejam with a nice cooperative twist (I'm telling you, those shove mechanics before were great).
