Underside is a Mother-Style RPG currently being made by myself and two friends.

We have been working on this project for quite some time. We currently have a full original soundtrack for the game, composed by myself and a friend (who prefers not to have his name online) with special musical talent thrown in from the Youtuber Brent "BrentalFloss" Black.

We haven't decided on a release date yet, as the game is still in-the-works. The album will be sold separately alongside the game.
