Trivia

 * The Electroman Adventures sneak peek did not feature the destructible blocks that were in the finished version, and one of the columns before the ship section was slightly modified.
 * Secret coins in pre-1.6 levels either modified the level itself showing features that didn't exist in past updates or were placed remotely in the level in already possible to reach locations.
 * This is the first update that introduced two levels, the second being 1.9, and the third being 2.0.
