Internal Clock is the 60th level in Chip's Challenge Level Pack 2. Largely, the level is a giant itemswapper, trading boots, keys, and eventually chips, but complicated by the addition of an "internal clock" - a fireball clone machine - in the Eric Schmidt tradition of being tougher than it looks. The quickest route will make the fireballs almost meaningless. The Decade Message for Internal Clock, originally from Scoundrel in CC1, doesn't suit the next level, Icy Moat, too well.
