One button. You are already swinging — the only question is when you press.

A press takes an anchor ahead or lets it go if no anchor is in reach. In free flight a press can find you a safe anchor again.

Walls bounce you and take speed while you are holding on an anchor. They end the run when you are not.

What is the goal oft the game?

There is no target, no finish line. Just enjoy getting into the flow, gaining speed when latching in the right moments, and get as far as possible!

Post a screenshot showing how far your latching got you in the comments!
