The Storm

Quite a refreshing short experience, dealing with more than your usual gore+lovecraft horror trope.
Very good in doing what it does (there is no way for me to address it, without revealing the coup de théâtre), despite some minor writing flaws (Spoiler - click to show)(telling us how we feel. I was perfectly unsettled without being reminded I am horrified or that a shiver runs through my spine).

My suggestion to you is: play it! It is extremely short (coffee-break IF), and will add a thing or two to your IF and Horror experience.
