"Wiggling" up ladders and narrow shafts is key here to maintain the horizontal jumping speed when exiting them. I
believe this is also the first known use of "pre-phasing" [actually delay-phasing], although it's a very minor use
(first brick on the way back). There are some crates that either get in the way or help you out, I tested phasing
certain ones to make the trip back quicker and this is what I found to be optimal.
If you took out an extra block on your way right, on your way left, would you have been able to jump over the spring
instead of pausing a moment?
In terms of distance you can travel, jumping takes several frames longer than just walking. In some cases it's better to
just wait a couple frames instead of jumping over it.

The level can be split up into a few sensible paths to travel down. I tried three different routes: One with six cycles
(two passes each for the outsides and center), one with four cycles (one pass for the outsides and two for the center),
and one with three cycles (one pass for each section). The one with four cycles turned out to be the fastest.
I tested a lot of the borderline gems (ones that could be grabbed on another pass) but let me know if I missed anything.
Here's a 1 second improvement on level 31:
This route uses 2 cycles instead of the original 4, simply splitting the level in half.

The level is laid out in a pretty sensible order already, it's just collecting the gems between the ladders that
required some testing. A stunner pops up in a really nice spot again, but I don't think getting it actually saved any
time.

Level 33. I don't think this is how the level's supposed to be beaten...

I'm not crazy about it, but this is the first idea that comes to mind:
Here's my first idea
The batbots really dictate whether a route is practical or not. They tend to create a lot of traffic above the 6 gems on
the ground and love blocking up narrow passages, so the route depends on their placement when you reach that area. The
reason I collect the last 3 gems in this order is because a batbot will always get stuck in the nook with the last gem,
and I have to coax it out by moving to the right. This is a modified version of the route that Nach posted and it was
the quickest out of the 3 routes I tested.

I kind of brute-forced this level. It matters which side you do first because the spinner placement can change and the
stunner may help more in one side than the other. The spinners also change whether a clockwise or counter-clockwise
route is faster, so I tried every combination and this was the best one.
You seemed to waste a couple of frames getting this gem. Did you fall down farther than you had to before flying out?
  • slamo: Hmm...I think you're right here, I landed, yet waited a couple of frames to take off. I can't remember if
    there's a good reason for that or if I just made a mistake.

I did 36 and 37 yesterday, I won't post the videos because they're mostly linear and only required small tests. 38 might
look familiar, here's my idea for it. Note that there's a secret passage in the bottom center through the stone, but I
cannot immediately enter it because of enemy placement, so I built this route avoiding that.
Getting the stunner saves a ton of time.
I deviate from the route to the green teleporter by going to the left and doing a teleport-grab on the nearby gem.
Fuel management was more important here than I anticipated. If I used all of it as fast as possible I wouldn't have
enough fuel to make it up to the exit, so I do some walking (the conveyers at the top helped as well) to save it for
later. The last gem is grabbed as the fuel hits zero.

I don't see a better way to make it through the pyramid...I tried going along the left side first instead of the right,
but it was almost a second slower. This route seems to flow a lot better. It's fairly easy to figure out if a route is
faster or not by simply adding up how many blocks you have to phase through - dark reds count as 2 and it's possible to
backtrack through 3 phased blocks.
