Wow! A boring premise turned into a game that's actually SUCH a good time. You're stranded on an island after a plane crash, and you're trying to make it to the top of a volcano together to be rescued.
The stamina system is what makes it interesting. As you play, your hunger grows and eats into your available stamina. You can stave it off with food of course, but would you rather late until later or now? Same thing for other elements that eat your stamina bar - fire, ice, poison, etc.
Then the proximity chat makes it a blast. You can chat to each other if you're close, otherwise you just hear random screams and stuff from far away.
My only gripe is having to wait a while for revive if you die early, plus runs take up to 2 hours with everyone. But such a fun party game!
