i'd like to warn you for a few bugs:

when you get the drill to irrigate, be careful and save before you start, there's a few spots you can drill, but it will crash the game... always a good idea to save after every chapter anyway.. kinda does it automaitcally but not often ;-)

oh and if a character dies and you still need them it may crash the game as well... happened about 2 times with me.

other than that it's a great game with a good few hours (days)

and on my third run i still find new things happening with decisions you make, so well worth it

enjoy
