The game is very short. There are just 10-15 items to be found and 4-6 puzzles to be solved.No acrobatics involved and very simple shooting of dangerous turrets. Even 1 of the achievements is for "finishing the game within 60 minutes", and I would expect most players to get through it in no more than 2-3 hours.

It is, however, generally well scripted, well written, well narrated and well executed. The game's world is nice and atmospheric, and I was really curious, what is the mystery behind all of this. So, yes, I have enjoyed it and I can recommend it, if you are willing to pay $5 for such a short experience.

I've said "generally well scripted, well written, well narrated and well executed" because it has a few non-critical shortcomings/bugs. 3 of those are technical, and I would expect them to be fixed soon:
1) it's unplayable (I can't look/turn side to side and I even can't access the menu and exit the game) with my Logitech F310 gamepad, which is probably most common for PC, though it doesn't matter much, as anyway, keyboard+mouse seem like preferred controls here;
2) the hints (at least those for getting the axe) are misleading, as they appear in places from which you can't even see the axe;
3) the achievements are currently broken for me (Win 10).

The main problem is, that it ends like a demo. There is a distinct difference between ending a chapter with an opening for a sequel/continuation, and just saying: "... to be continued". Unfortunately, the ending here is much closer to the 2nd, than to the first. It does solve at least part of the mystery, but it doesn't do it right, IMO.

If this was a free demo and achievements were fixed, I would give it 9/10. Taking into account it's length, price and the poorly done ending, it's barely passing my mark, getting 5.5/10.
