Reflex
Time your input as an expanding pulse crosses the target ring.
Watch the pulse expand from the center. Tap when it crosses the marked target ring. Each round is judged as Perfect, Good, or Miss based on how closely the pulse matches the target. Complete 20 rounds and build a combo for a higher score.
Mobile: Tap anywhere inside the game area during an active round. Desktop: Press Space or click inside the game area during an active round. Start, Resume, and Play Again use their own buttons.
Perfect earns 100 base points. Good earns 60. Miss earns 0 and resets the combo. Perfect and Good increase the combo, unlocking higher score multipliers as the streak grows.
Follow the marked target ring rather than a decoy. Later rounds can change pulse speed and add decoys, so judge the approach you see now instead of reusing an opening-round rhythm. After a Miss resets the combo, use the next input to establish a new streak rather than chasing the points already lost.
If your combo is 4 and the next judgement is Perfect, the new combo is 5 and the multiplier is ×1.25: 100 base points × 1.25 = 125. A Miss awards 0 and resets the combo, so timing affects both this round and the multiplier you carry forward.
Pulse Junction asks for one timed input as an expanding pulse crosses a marked radius; it does not ask you to steer or hold the pulse. Across 20 rounds, target position and speed change, and later rounds add decoy rings, making target recognition part of the timing decision.
