It wasn't based on anything outside of letting jam constraints push me around. I do kinda want to make more games with these characters though.
I did enjoy it! I used it as an opportunity to sketch out a lil' game editor. (There's a secret hidden thing if you're curious, press "p" in-game to see the editor I built to design all the in-game scenes, can't save with it on itch, but I used it locally :) )
