The Eyes appear in this world again, and you'll encounter a new enemy: the Array, who slides and does a small jump to confuse you. This is a very difficult world, particularly because the Bricks are back as well.
Stage 1[edit]
Lots of Arrays will attempt to trip you up, but don't panic. You can safely ignore them most of the time, as they won't jump on you if you just continue running ahead without turning. Be extra cautious with Bricks, they appear even in gaps and you will lose a life if they catch you there.
Stage 2[edit]
The bonus jetpack is easily obtained at the start of this stage. The rest of the stage contains an increase in the number of Eyes and Arrays, and some of the gaps will be filled with Bricks.
Stage 3[edit]
This stage can be frustrating. The Bricks on the gaps will try to prevent you from crossing, so you need to look for a safe route across the gaps where they don't appear.
Stage 4[edit]
The final stage contains a little of everything that this world has thrown at you so far. Just as with the last stage, there is a safe path that you must seek out when attempting to jump across the gaps so that you don't get stopped by Bricks.
Boss[edit]
Once again, the boss strategy does not change. The only thing different this time, is that you are required to defeat the boss three times in order to proceed to the next world.
