Dengeki Online just announced detailed info on a new otome game from D3 Publisher, and it’s in the survival suspense genre! It’s not a horror survival like Resident Evil (thank God because I don’t think I could play it), but the premise is that the heroine gets stranded in an old school building in the middle of nowhere with several male students, a teacher, and a teaching student, and has to find her way out while a killer calling himself “Kamen no Shinigami” (The Masked God of Death) starts to attack them.
Kurayami no Hate de Kimi o Matsu is slated for a fall release for the Nintendo DS, and seems to have a puzzle component as well. To get out of the old building, you have to solve some puzzles using the touchpad and collecting items with one of the six guys you were stranded with. To make things even more nerve-wracking, the killer is one of the six guys you can choose!
The site has character info, and the Dengeki site has a bunch of screenshots showing the setup.
