Round and Round Inc. launches on Steam for PC
Murbong Studio's black-and-white incremental game tasks players with guiding 8.2 billion people through a revolving door.
Murbong Studio released the incremental game Round and Round Inc. on PC via Steam on November 13, 2026, according to gamespark.jp. The title is presented in a black-and-white visual style and is built around funneling crowds through a revolving door.
The objective is to get all 8.2 billion humans to enter, earning money that can be spent on enlarging the door and swapping out its blades. Players can turn the door manually in circular motions or hand control to an automatic drive.
Blade types include straight, bent-tip and spiral shapes, each pulling people in differently. Spinning the door at high speed sends people flying, and chaining those flights builds a “Hyun combo”.
Reincarnation and an ending
Reincarnation grants spin energy, which is used to pick contracts and speed up the next run. Reaching all of humanity triggers an ending that reviews the player's records.
The game supports Japanese and costs 705 yen, with a 15% discount bringing it to 599 yen until November 20. A demo is available, and progress carries over to the full version.
According to Steam news, the maximum number of crowd members displayed at once was raised from 200,000 to 1 million during development.
