PASS: Precision Timing

One tap. One moment. That is the whole game. A mark waits at the bottom of the screen. Above it, barriers slide, rotate, pulse and orbit. Tap once and the mark travels straight up at a fixed speed, through whatever happens to be in the way. Choose the wrong moment and it stops. Choose the right one and it passes. There is nothing else to learn. 100 HAND-TUNED LEVELS Six families of obstacle, introduced one at a time and then combined. Every level has been verified by simulation to have a real opening — none of them asks you to hit a window that does not exist. PERFECT Passing is one thing. Passing through the centre of the opening is another. Perfect is marked on the level grid by shape rather than colour, so it reads at a glance and survives a greyscale screen. ENDLESS When the 100 are done, the same six families keep coming, generated from a seed, until you miss. WHAT IS NOT HERE No accounts. No adverts. No in-app purchases. No lives, no energy timers, no streak reminders. No analytics, no tracking, no data collection of any kind. The app never connects to the network — it plays entirely on your device, and everything it remembers stays there. Sound and haptics can be switched off. Light, dark or system appearance. Observe. Time. Pass.
