0:00 Jungle Boogie (normal exit): This level is the first to use the no-time-limit cloud to fly around. It's not too overwhelming if you know every enemy's behavior and attack patterns. The second half also has a little fun with Lakitus poking their heads out of the ledges and throwing stuff at you. If you were getting tired of the jungle music, don't worry, it's pretty much done now.
3:50 Jungle Boogie (secret exit): There's not too many places to even look. Maybe a wide open area wouldn't look obvious, but hey.
4:48 Blue Switch Palace: This level has fun with recoloring the lava to look like water. Don't worry, it is actually water. I mean, for a vanilla hack, it's the best way to make non-cutoff waterfalls. And yes, to get every Dragon Coin in this switch palace, the level has to be played twice.
7:12 Temple of Jaya: This level is entirely skippable in order to filter out a game-breaking bug in which you couldn't get past the third world. But it's still playable. It's actually very long for an early game level and makes good use of Layer 2. The lava gets boring to wait for (sort of) and the water tide may make no sense in the real world, but works strangely well in a video game. The last section just has you ride a platform and jump on more vines. It's still a lot, but even then it's reasonable.
