Find the exit of each maze while random tiles flash a warning under your feet. Move off before the warning runs out, or lose a life. Mazes get bigger and hazards get faster with every level.

Reaction time — how quickly a person notices something and acts on it — is one of the oldest and most reliable measures psychologists use to study attention. It shows up everywhere from sports training to road-safety research, because the gap between "seeing" and "responding" turns out to be a surprisingly stable, measurable trait that changes with fatigue, practice, and focus.
This game turns that idea into a maze. Every tile you might be standing on can flash a brief warning before it becomes dangerous, and the only way through is to notice it and step away in time — there's no way to plan around a hazard that hasn't appeared yet. As levels pass, the maze grows larger and the warning window shrinks, so the challenge shifts from simply finding the exit to staying alert while you do it.
A run ends when all three lives are lost, and scoring rewards both successful dodges and full mazes cleared. Runs are entirely local and instant — nothing to download or install — and a top score can be saved with a nickname to the site's global leaderboard, ranked against every other player's best.
