Off is a very creative RPG following the Batter on a journey through a surreal world. I don't know what else to say and don't want to spoil anything. There is an offical release on Steam with a soundtrack made by Toby Fox but the original soundtrack is super iconic for the game. I think translations (since the game is originally in French) of the original game are still available online. If you like RPGs, especially games like Undertale, this is definitely a good game to try out.
