The game seems very nice and chill.
The art and music go very well together.
The number 1 thing it needs, imo, is a tutorial to explain how the pieces work, and what the controls are (the right-click deletion, for example, is not explained).
For a game jam, this could even be done just by updating the itch.io page.
I've seen plenty of games in this jam with the tutorials outside the game.
