Windstack: the sky is five rivers, pick the right one

Each altitude band blows its own way. You cannot steer, only climb and sink. Collect the numbered rings in order, then touch down gently on the striped pad.

Keys: Up, W or Space burn. Down or S vent. Enter launches or continues, R restarts. Burning uses fuel, venting is free. Land with a sink speed under 80 px/s. Arrows show wind direction and speed in px/s.
