DISHARMONY is a mostly-solo project whose idea originated all the way back in December of 2015, and has been in development since April 2018.
The game itself takes a ton of inspiration from the Mother series, as well as the Legend of Zelda, but its battle mechanics are more reminiscent of Stepmania and Guitar Hero.
The story follows a character named Tay, who is looking for his older sister who's gone missing. On his journey, he gains the ability to enter people's dreams, where he has the chance to defeat their nightmares. It takes place in a kind-of-fantasy world with sci-fi elements. There's some psychological horror aspects thrown in as well for good measure.
Fair warning-- the game might be a little difficult if you aren't used to playing rhythm games, it does get a little brutal at times- but most people seem to pick up on it pretty quickly, and further accessibility options are going to be added in the future.
