This is a simple horror game, playable in under 15 minutes.
It seems extremely merciful; I completed it and won on my first go-through. I tried a second time, deliberately choosing what seemed like the few bad choices available, and found the game was quite good at hinting me toward the satisfying outcome.
The writing is good, although I could use a little more story. I'm not sure why things are happening, and the island has a number of nooks and crannies which could provide exposition for those seeking it. The game gives small tidbits which should be expanded upon, delivering more background and more plot.
There are a number of areas implemented which don't provide anything, and I'm not sure how they advance the game or the story. It would be interesting to have these side paths provide insight and context--perhaps a page of a diary entry here or there--in the same way that Miasmata and Bioshock did.
I think this small twine narrative would be good for a newcomer, to give them a basic sense of what the medium does without being difficult or frustrating.
