“...Ah, you saw us, didn't you? (Wait, there was still a customer here!?)”
🎮『ARCADE: MIDNIGHT』
A slightly worn-out game center tucked away in a corner of the city. By day, it's an ordinary arcade, but once closing time passes, it transforms into another world.
12:00 AM. After the last customer leaves and the shutters close, the game machines begin to power on one by one of their own accord. What appears on the screens is not just a game. There, the "World of the Arcade" itself unfolds.
—By being played, the world keeps moving.
