Brainstorm Inc. (headquartered in Kunitachi, Tokyo; CEO: Takayuki Nakamura) will exhibit its new game in development, “Marble Scramble — Aliens at the Crossing,” at BitSummit PUNCH 2026, one of Japan’s largest indie game festivals, to be held May 22–24, 2026 at Miyako Messe in Kyoto, Japan. At the company’s booth (Booth No. 3F-C19), visitors can enjoy a hands-on, playable prototype of the game.

About “Marble Scramble”

“Marble Scramble” is a new hybrid-casual game set at Shibuya Scramble Crossing — the iconic Tokyo intersection known worldwide as one of the busiest pedestrian crossings. It blends three elements: simple tap controls, a living crowd simulation, and a character-fusion system that breeds new characters the more you play. Anyone can pick it up instantly by tapping and connecting same-colored characters, while chains and auto-coupling deliver satisfying high-score bursts, and a collection of “creepy-cute” aliens that evolve across generations gives the game lasting depth. Under the theme of “the crossroads of life,” its world is colored by characters that carry a touch of social satire.

Public in-browser release during the event — playable on PC, tablet, and smartphone

“Marble Scramble” is built as a web app, and the game will be made publicly available throughout BitSummit PUNCH 2026. Whether or not they attend the venue, anyone can play it directly from a browser on PC, tablet, or smartphone.

BitSummit special project — an AR app that lets you “take home” the characters

As a special project during the event, the company will run an AR app tie-in that lets players summon the characters they collected in the game onto their own smartphone. Visitors can “take home” a favorite character created through fusion at the booth, see it appear in the real world through a dedicated AR app, and capture and share it on social media — a limited-time experience available only during BitSummit.

Seeking publishing and collaboration partners

“Marble Scramble” is currently at the prototype stage, and its core fun has been proven through in-house playtesting. Toward commercialization, Brainstorm Inc. is broadly seeking partner companies — primarily for publishing, as well as for graphics enhancement, promotion, and multi-platform expansion. Please come and try the prototype at the company’s booth at BitSummit.
