AFTERCUT

One cut. Beautiful chaos.

Slice a yellow cable and let gravity take over. Drop a weight, send it swinging, or launch it off a springboard. Break every red crystal — and keep the blue heart alive.

You get one straight stroke. It can cut more than one cable. Sometimes the cleverest move is leaving one hanging.

Six little disasters

Start a chain explosion, roll down a ramp, swing around a pivot, bounce against gravity, release two weights together, and attempt a careful demolition.
