I bought this two weeks ago.
It's completely weird, and the manual and in-game explanations are apparently purposefully vague.
The levels actually reminded more than a bit of the remake of The Sentinel.
It's the opposite of an action game, in fact it's painfully slow, but the main thing it has going for it is an incredibly bleak atmosphere (intentionally).
Well, it is Russian, and I suppose they might see it as a holiday resort simulation, I don't know.
I find it mildly interesting, just to see what weird ideas they come up with next, but in no way is it captivating, although it's fun now and again.
