wow this is pretty cool! thanks, does it make sense to add cljbox2d as a dependency to my little game even if I don’t plan on using any physics simulation? Just for the quil-extras there. this is very useful on any type of game.

You'd be pulling in jbox2d but maybe that's not a big issue for you. Or just copy the namespace to your own project.

Maybe you also find this useful, code to split sprite sheets back into individual images https://github.com/lambdaisland/puck/blob/main/src/lambdaisland/puck/sprite_splitter.clj

A lot of sprite sheets you find don't come with the necessary coordinate information of what's where on the sheet. I used this to unpack them, select the ones I need, and then repack with existing tools. If have to look around to see what I used for that though
