I would say this is a very cozy game. It is one of the best games in the jam.
If you want to improve it then here is some areas:
1: The riverbench (where the ground meet the river) could use more work.
2: The bridge/water transaction could use some work. It looks like it is floating.
3: The water in the river looks like it stands still. Maybe animate it?
4: Some background music could be nice (but not to loud)
