A 2-week dev sprint, programming fully outsourced to AI, and over ¥100 million "spent"!? The forbidden game is back—with a mysterious falling-block mode! Clear the whole board except Wilds using three princesses' quirky powers: Lovely Heart, Starlight Song, Storm Wind—order matters! Japanese only.

Trends
Concurrent players on Steam, one reading a day at about 15:00 UTC since Sep 9, 2026. Before then readings were taken at different times of day, spanning 0 hours, and Steam concurrency runs about 1.8x higher at its daily high than at its low — so some of the movement across that stretch is the clock, not the game.
