This visual novel is part of the Single Choice Jam. In it, you play as a researcher on an underwater base where everyone has been slaughtered after a humanoid creature was dragged up out of the abyss.
The highlight here is seeing the beautiful artwork, of which there is quite a lot for the brevity of the game. It has a style that is distinct and fits well with underwater horror.
The storyline is gripping and intense. I did find a couple of typos, and some analogies didn't land for me (specifically a part about 'not an oz' when referring to information). Overall, though, I was glad I played and found it interesting.
