Walk around, talk to some people, be vaguely confussed about what's going on. Get into a very small amount of so-so combat, talk some more. Game finished. Apparently there's more depth to it if you play it again but frankly if I'm not sure why I'd want to bother. Short too, feels like the first act of what could be a decent full game.
Played it quite obsessively for a few evenings and then sort of ran out of things to keep me interested. Good at giving you more and more stuff to unlock but most of what you're doing is just grinding to unlock the next thing. Combat is so easy it's pointless.
