Corpse Party, a recreation of '96 RPG Maker-made survival horror for PC-9801. Nowadays, the game pretty much tells the story in a similar setting, the 16-bit climate is rebuilt perfectly and the genuine sense of fear can be felt under appropriate conditions.
So, pretty much - RPG survival horror with vn elements. You perform various tasks in different chapters to pass said chapter. Each chapter contains several bad endings, each of them creepier than the previous, with only one way to earn a good ending - and if you fuck up somewhere in the process, you won't know until you face a bad ending.
The story's pretty creepy, though.
