I really love the aesthetic of this!
I think its pretty common in a game jam to see games that try to do a lot of different things but lack polish, since people want to hash out their ideas as quickly as possible and move on. Here, its clear that you took a relatively simple single-scene idea and spent plenty of time treating it right, and the results look and sound great. I was also confused whilst playing, but it was such a joyful little scene to watch play out that I didn't mind too much. With a little extra time to spend introducing the player to mechanics gradually, this game would really feel complete.
