that was... surprisingly fast. after a couple of issues which i actually didn't understand the cause of and just ended up closing and reopening things to fix, i think i went from zero technical understanding to creating a cube player with synced movement in about 30 minutes. and the SDK looks damn good.
don't want to place too many bets on it. the platform has clearly improved a lot. the main video tutorial from just May 2021 is already out of date on the names of several menus and buttons, but it looks like every change has improved clarity or added interesting new features. maybe i'll step into the networking side of Satellite a little sooner for this prototype, by trying this out!
