Spike Chunsoft continues their Smart Sound Novel series with a port of Nine Hours, Nine Persons, Nine Doors. This game is the first title in the Zero Escape series and was originally released for the Nintendo DS back in 2009.
Nine Hours, Nine Persons, Nine Doors has the same story as the DS game, but it’s only the story. The escape the room puzzles were removed. The game has some other changes like a comic style presentation for conversations and a handy flowchart that allows you to jump at different points like Virute’s Last Reward.
The graphics were also updated with high resolution images. Nine Hours, Nine Persons, Nine Doors is 1,000 yen and available on iTunes right now. It looks like it’s a Japan-only title at the moment.
