(edited) 1 star until crashes are fixed.
Other than the crashing, the game is fun, a seamless move from the first one(which I also own) and I decided to buy both games on GoG to support the devs (so they maybe upgrade all the other dah games too)
But this crashing BS @ the bongwater fight (no way to prevent crash, trust me, tried everything) and the exact same crash on various cut-scenes and anywhere there is 'smoke' or 'fog' (i think its a gpx memory leak issue related to the fog particle physics)
I refunded both games, but am buying it again now in the hopes they fix it (while it is still on sale) and am just really hoping the issue is fixed inside the 1 month 'window' you have to return.
update on 23/01/02 seems to have fixed it, game seems to run smooth now, at least not with constant un-avoidable crash at bongwater.
