Time the pulse
Watch the expanding pulse ring. Timing determines whether the move is judged EARLY, PERFECT, or LATE.
A gentle ascent
Climb with every pulse.
Jellyfish Climb is a free browser game about rhythm, direction, and choosing when to move. Collect plankton on the way up, work with changing water currents, and reach the goal while time remains.
Game overview
Simple input, careful timing
The game can be understood without loading its canvas: click or tap to make the jellyfish pulse upward. Aim with A and D on a keyboard, or tilt a supported mobile device. A well-timed pulse climbs more strongly than an early or late one.
Read the current
Upward and downward flow phases change over time, so the same move can have a different result.
Build the score
Collect moving plankton, then reach the goal. The remaining time determines the Time Rate applied to the plankton score.
