This is not safe to play until final version is out. Dev seems to have fetish for making old saves unusable. It's 3rd or 4th time he's pulling that stunt. Who's not to say that 0.99 to 1.00 wont require new game? Not touching till "completed" tag is there. Maybe will wait a year after that, just to be safe...
Besides it's way too buggy.
I can't trigger the renewal of the Artic Cafe.
Someone needs to give a parcel to a character that has disappeared.
A sandbox in which you are free to do the tasks in any order you like, but if you don't follow a particular order you get locked out of certain events, is a bad sandbox.
A kinetic novel would be preferable to this buggy sandbox.
Besides some hints don't get deleted from the quest log once the quest is completed!
(For instance the ethernal "Talk to Fred" with the only option on Fred being "I'll come later")
