NN555Sync

PulseSync is an offline rhythm game built around clear visual timing, simple lane patterns, and accurate touch control.

Choose from 40 handcrafted practice levels across four chapters. Each level focuses on a different timing challenge, from steady taps to alternating lanes, overlapping doubles, and short hold actions.

The game is designed to stay readable even when muted. Three wide lanes, a clear judge line, and visible beat markers make each pattern easy to follow without external songs or online content.

Features include:

* Fully offline play with no account, ad, payment, or song download requirement
* First-run calibration with a local offset suggestion
* Five judgment tiers: Perfect, Good, Early, Late, and Miss
* Combo tracking and detailed end-of-run analysis
* Weak-segment replay for focused practice on the hardest 15-second section
* Pause and resume flow with a three-beat countdown
* Settings for sound, haptics, left-handed layout, reduced motion, larger judge line, and track labels
* Local progress storage for level completion, best accuracy, and recent results

PulseSync keeps all gameplay data on the device so practice stays private and available offline.
