I'm not sure what to say here. The puzzle are sufficient, with a few being rather interesting. The story does push you forward but the timer is only an occasional threat.
The ending... I don't know what to say about it to avoid spoilers. I didn't love the ending. All I will say, is that while I was surprised by it, I was left underwhelmed by it from a story perspective.
Still, at the end of the day if you have even a passing interest in the fetish you might as well check it out. If the puzzles are too hard/clunky you can skip them and the game took me around 40 minutes to beat.
