The game features Masaru Ōchi as a producer and Tomoko Sasaki as composer.

The game is an homage to Sega's ROOMMANIA #203 Dreamcast game, released in 2000. As in ROOMMANIA#203, players will play a god-like character who throws invisible balls into the room of the protagonist "Neji Taihei." Ōchi said that "Project One Room" will be able utilize the PS4 so the balls follow the proper laws of physics.

The original game received a PlayStation 2 port in 2002 and a sequel titled New Roommania Porori Seishun for the PS2 in 2003.
