Pretty nice, tiny game fitting for a jam.
With some more dev time it could surely benefit from more gameplay variety. It's also happened to me during jams that I try making something with procedural elements and end up running out of time to implement content even if I have the basics laid out.
I like that it presents a theme and sticks to it for the different aspects of design. It also seems that the systems hold up quite well during normal gameplay not trying to break things, which isn't a given in jams. Good job!
