Hmm, I need a hint since I spent about 20 minutes matching symbols on the two computers and you mention the playtime being less than 10 minutes. Lovely atmosphere though.
Hmm, did you see a really large flock of birds? And did you look around at the mountains during your last 10 minutes?
Oh, OK I got it that time! Not sure what I did differently- very cool ending though.
Thanks for sticking through it! Possibly it could have been a bug.
