Welcome to Amaluuk research station, we hope your stay is a productive and pleasant one.
I originally planned to give this an 8/10. I actually quite liked the implementation.
And then I had a creeping feeling that made me think, "It's as if I've seen this stuff before."
Surprise, surprise: I had. In the Penumbra series.
Everything from the setting (Greenland), to the snowy exterior, to the dead dogs in the kennels, and yes, even to the cheap, gimmicky sequence where you have to stay under a timed light that just happens to move down one at a time.
So I'm rating this a 6/10, because while they coded it decently, they stole a big chunk of things from Penumbra. Shame on you.
Update: Rated 1 since they decided to delete my comment they didn't like.
