Ghost Pass is a portrait-mode rhythm-stacking mobile game. Its core mechanic focuses on precise block placement and extreme stacking height. Players control a colored prism block that slides left and right at the top of the screen, tapping at the right moment to drop it. The dropped block overlaps with the tower top below; the overlapping part becomes the new layer, and the tower grows taller while the sliding speed gradually increases. If the overlap is too narrow for a stable connection, the round ends immediately. The game supports pause and restart, and automatically records the all‑time high score, encouraging players to push for higher tower heights under tense pacing. Simple and intuitive controls demand good anticipation, quick reflexes, and steady nerves—easy to pick up yet offering strategic replay value for repeated challenges.
