Due to a bug in the System.clock method (basically it gets suspended whilst waiting for user input), it is not currently possible to add timings.

var player2 = Input.text("Player 2, please enter your name : ", 1)
if (player2 == player1) player2 = player2 + "2"
var words3or4 = words.where { |w| w.count == 3 || w.count == 4 }.toList
var n = words3or4.count
var firstWord = words3or4[rand.int(n)]

Sample game:
