cut a swinging pendulum at the right phase so it falls into a moving cup
Rope Cut begins with a weighted object attached to a pivot by a fixed-length rope. Gravity drives pendulum motion and tension keeps the weight on its arc. Cutting removes that constraint at the current phase, converting tangential speed into a free projectile that must descend into a horizontally moving cup.
Use Left and Right before cutting to shift the cup, then press action or Space to sever the active rope. The rope cannot be restored during flight. After a catch or miss, a new pendulum begins with a different angle and cup direction. Reset clears the sequence and score while preserving the browser best.
A clean catch awards points for remaining cup width and efficient timing. Cutting with strong useful tangential speed gives a swing bonus. Missing the cup or touching a hazard removes one life, then play continues with a fresh rope. Consecutive catches raise swing speed and make the moving target less forgiving.
Cut while the weight travels toward the cup, usually before the lowest point so its velocity has both horizontal reach and time to fall. A very early cut lacks speed; a late cut sends the object away. Move the cup only for a modest correction and compare the previous free-flight arc before choosing the next phase.
Touch controls keep cup adjustment and cutting separate. Debug mode waits for varied swing phases, producing catches and misses instead of a repeated canned arc. The text snapshot exposes pivot, rope length, angle, angular velocity, cut state, free velocity, cup bounds, score, streak, and lives.
