A group of teenagers enter an abandoned mansion on the outskirts of town to see if it’s haunted… an unimaginative set up for a horror tale, but thankfully it’s not indicative of the rest of the game. Released in 2009 by the Japanese developer noprops, Ao Oni has since gained a cult reputation for its inventive scares and challenging puzzles. Given that it’s made in RPGMaker XP, the game’s not Amnesia-levels of scary, but it squeezes a lot out of the aging engine to provide a suitably creepy backdrop for the puzzle-solving.
Everything you need to play Ao Oni is available at its homepage, including the RPGMaker XP runtime. There are Japanese, English, and Italian language editions of the game – just download your preferred translation, unzip, and run (after installing the runtime, of course). Keep in mind that different versions of Ao Oni vary greatly in terms of plot and design… older versions are available from other websites if you’re interested (but beware of spoilers).
