Nice work on this one! I'm impressed by just how lengthy of a story you've created here, especially under the time constraints of a game jam. I thought the mechanic of combining actions to create new ones was really interesting and has lots of potential to be explored even further!
Since the game is controlled entirely with the mouse, I think it would be nice if the buttons/sprites you can click on had a distinct/highlighted sprite when you hover over them; that way, it's easier to tell what is clickable and what isn't.
Great job!
