Plan then Run

Every monster sleeps with an alarm clock, and the number printed on it is the moment it wakes. Drop a few monsters onto the board, choose their numbers, then press run and watch the whole board count down from 5 to 1.

Hit Every Goal

Three kinds of goal: a box on a plate, a bullet on target, a beam held in place.

Plan Wisely

Same board, same monsters - one number apart, Failed on one side and Cleared on the other.

It All Comes Together

Later boards fill up with monsters, and one countdown has to walk every one of them through in the order you wrote.
