About
SETSUNA is a precision timing game where every millisecond matters.
Your goal sounds simple: stop at the perfect moment.
The challenge is not.
Built around a 0.001-second scoring system, SETSUNA tests your focus, rhythm, and reaction across multiple competitive modes:
Classic 10-Second Challenge
Start and stop as close as possible to exactly 10.000 seconds.
Split Mode (5 Sections)
Hit five timing checkpoints in one run (2s / 4s / 6s / 8s / 10s).
Consistency wins: lower total error ranks higher.
Setsuna Mode
Wait in silence, then react instantly when “GO” appears.
Too early or too late, and the run is gone.
Practice Mode
Train freely without affecting your records or rankings.
