The Omniverse Project
The Multiverse Project (tentative title) is a game being developed in RPG Maker VX by Chaotic Infinity Development, spearheaded by DerxwnaKapsyla. It can be inferred that it takes place after the events of Touhoumon Faith & Prayer Version, but the time of events is irrelevant. The game focuses on the Abyss Dweller R.K. as he travels across the Omniverse to help keep stability among universes. Derxwna Kapsyla, the other Abyss Dweller, also makes appearances in the game, but is not a playable character.
The game is in sporadic development, and it is unlikely it will see release of any version anytime soon.
