The maze is invisible. Tap to send a sonar pulse, watch the walls flash for a breath, then steer through the dark from memory. Touch a wall and you shatter.
Every pulse lights the walls it can reach for a moment. Walls you have seen stay as a faint memory. Fewer pulses earn a full signal.
Dive from the Shallows to the Hollow: lasers that blink, blocks that drift, crystals that bend sound and shadows that hunt your ping.
A fresh daily maze, three daily goals and a streak that unlocks new pulse themes and soundscapes. Freezes protect a missed day.
Haptics tick as you brush a wall, echoes return from the dark. Plays offline, no account, no energy timers.
