Ohr Oni (2012)
Ohr Oni is an Ao Oni spinoff game created with the OHRRPGCE (Official Hamster Republic Role Playing Game Creation Engine), a program that was pretty popular in the late 90s/early 00s pre-RPG Maker years. It is made in the style of late-80s Famicom games like Sweet Home and MOTHER, so if you’ve ever wanted to be chased around by a very cute, chunky 8-bit Oni, then this is your chance. The game is veeeeerrrry short (for players on their second playthrough, it can be cleared in less than 15 minutes) and has two endings.
About the story
You were a normal Japanese schoolboy taking the metro to get to class, but after a strange earthquake destroys the train, you find yourself alone, trapped in the underground tunnels and surrounded by dead bodies. Try to find a way out, but don’t forget about the rumors of a big blue monster that lives in the tunnels.
