today was very much a my-body-seems-to-hate-me day. i spent a lot of time getting up and moving around. i added URP and ProBuilder to the jam project, and then i dug my head into the jump physics as i often get stuck on. i really really don't want to overdo this, but dang. i also want jumping to work correctly, and that is just always so annoying! i think i found a way to do it right that won't be too much more work, but if this isn't done by the end of tomorrow, i'm scrapping it for something stupid simple.
