Notes on Bonus World One Any%

For the most part I'll try not to mention things that should be obvious by watching my PB, but instead focus on decision points in the run, and nuances that may not be apparent from the video.

== CH3NO2 ==

For no-reset runs I take the standard route, and if the Starbot drops stars in my way, it means that I can hit 70% sooner and finish. For PB attempts though, I've tried to follow the Starbot as far as I could, as long as I didn't run directly into fire. Getting the full complement of stars from the bot can save several seconds, even if it's gone a bit out of the way.

As soon as the top section opens up, I run up there and collect those stars. Come back down, to the left of the red box. If I've had good Starbot luck, then I go down and collect the stars near the Big Star, then come back up and right, because by then that section will have stopped burning. Grab those stars, then come back left to the red box (which will have exploded by then), then back down to the bottom right if there are any Starbot stars there. If you get a slow pattern against an optimized PB, this is a heavy reset point.

== P4 ==

Squibbons uses Ember, who's the fastest character for this stage as a result of a glitch where you can activate her shield ability while picking up the barrel. See Squibs' PB for an example of that route. I use Coldsnap instead, because they're not much slower, I'm more familiar with this route, and some of the lost time is made up by not needing to change characters going to the next stage.

Coldsnap makes it so that for two of the lasers in this stage, once you hit them with the ice crystal they stop firing entirely for the rest of the stage; the one on the left side near the spawn point, and the right-side laser that's firing over the big conveyor belt.

The primary thing with this route that may not be evident from watching my runs is that the orange box in the top-right has timing that will often kill you if you're not keeping an eye out for its explosion. For no-reset runs after collecting the rocket I will often wait for it to explode before crossing up.

Being a Super Metroid runner I'm a big fan of the "hero shot" I make with the ice crystal from the bottom right corner to the saw blade in the upper right.

While holding the barrel, sometimes the red box in the top middle will not kill me. I have no idea why, but for PB attempts I'll often take the risk, hoping it doesn't kill me.

For some reason this setup makes the Starbot stand still. I take full advantage of this. I collect as many stars as are convenient from the conveyor at the end of its cycle, then run through the rest to the finish.

== O2F2 ==

If you get no extra stars from the Starbot on this stage, you'll need to wait for the stars on the far right side of the stage to appear before you can get 70%. This costs several seconds, and is a big reset point for improving an optimized PB.

Otherwise, the stage is waiting on the "fuse" to burn from the bomb placed in the lower middle, so frame saves in the first half of the stage until that bomb is planted are really all that matter. On the PC version you'll need to wait until all flames are finished burning before the game will let you move on.

== AgN3 ==

I was using Burnstar until recently, but started using Ember, as a result of finding a slightly faster strat in IL practice. As a bonus, it reduces menuing necessary for the next stage, which uses Ember already.

At the start if you can save frames on moving around corners, that can help you get on good cycles later in the stage. Case in point, when you get to the far left, if you're quick you can make it through before the middle cannon fires. In my current PB I wasn't sure if I was fast enough, so I waited until it fired. Then on the way down from firing my top rocket, I wait for another fireball to go past before I run down. If I had made it past both of these, I could've got past the sawblade without needing to use the shield.

During the collection phase of this stage, you'll need to balance how long you stand in one place waiting for the stars to come to you compared with moving on and collecting a different set. You need All Golds on this stage, so this can depend on your Starbot luck.

One of the other big things to watch out for is not to block a fireball with your shield that you needed in order to make a path through the maze.

== Al2Me6 ==

Grabbing the lower left bomb and using it on the middle is slower for IL times, but seems to be faster RTA, due to the burn time after you grab the Big Star.

== C6H15B ==

If the Starbot happens to drop a star within reach of the second E of the giant EMBER, I'm able to hit 70% without stopping briefly next to the stage exit to get one more star.

If the Starbot happens to go into the lower right section of this level, that's likely a reset, cause then you will need to figure out how to fix the pipe switches on the fly. Fortunately, I think it's only happened to me once.

== KH ==

My IL PB for this level is with Burnstar, but it's by such a small margin that the menuing to change characters isn't worth it. I stick with Ember.

The manipulation of the Ghost Blocks is pretty subtle, but once you get a feel for them you can make their movement fairly consistent.

After laying the bomb next to the yellow box in the top right, I used to stand still briefly to move the Ghost Block by two squares, but recently I started just popping in to move it one square, so I can sneak by on the right side.

After laying all of the bombs, if I can I'll quickly pick up a few of the Starbot stars on the left side. There's a long goo fuse burning on the top left quadrant, and this can help save time at the end of the level.

See if there's a star directly in the path to the Big Star, so maybe you don't need to get all the way to 100% before making a run for it.

== ClN3 ==

The bomb up top is the long fuse for this stage. Any frames saved before laying that bomb will end the level quicker.

It's possible to get one cycle quicker than what I did at the start of my PB, but it's *incredibly* difficult. It's also possible to get one cycle quicker in the segment after laying the first two bombs, but that's also hazardous.

== C6H6N12O12 ==

Try not to die like I did in my PB.

It's also possible to use a bomb on the bottom middle crusher, but I prefer the rocket strat. You just need to make sure the crusher is far enough back to have the rocket ignite the yellow boxes instead of directly lighting the goo.

It would be faster to know how many stars there are in the top left, and run there as soon as you have enough for 100%, instead of waiting for the top right to finish burning.

== ArHF ==

Until recently I was doing a fairly vanilla strat every run, and I would follow the Starbot only as long as it was running around the bottom of the stage. If it went through the teleporter to the right side, or if it went up, I would keep moving on and just finish the level as normal.

Recently I started following the Starbot as much as possible, and doing the two-loop route seen here. Sometimes I can even make it a single loop, if the Starbot stays on the left side near the Big Star. 

If you need to make a second loop, the fireball launcher shooting down will be deactivated, so you can grab the stars in that area while only needing to worry about the launcher shooting right.

With this route, if you don't get enough stars from the Starbot you'll need to use the safe strat of shooting the second rocket to the bottom right corner to make the bomb available, instead of the strat shown in my PB of shooting the rocket on the top right to open up the way around.

If you get the bomb but don't need any stars from the top right, you can put the bomb on the lower left breakable block instead of the center one that will also set the goo on fire.

== C2H6Cd ==

The execution is straightforward on this stage, until the Starbot spawns. Stay with it as much as possible, since the stage will be softlocked if you don't spawn enough bonus stars. Avoid the crushers.

== C2N14 ==

Generally I try to make the Evil Toxos set fire to the trail of goo before I leave the center area. That way I can take an entire lap around the level area collecting stars, and by the time I start a second lap the goo will be clear from the top right.

The enemies can be manipulated, and it seems to be entirely non-random, but it's so subtle that a slight difference in movement can cause an enemy to take a different path that blocks the route you had planned.

In this case I got extremely lucky with the enemy patterns, and I was able to clear the entire stage in only a single pass.

Right at the start of the stage I clear the top right, and pause briefly to (hopefully) bait the blue Toxo to fire a rocket at me, destroying the breakable block. This can help increase movement options on the second lap.

When I get to the bottom center I run towards the Goo Toxo, then back off before he reaches me. That way he continues to follow me around clockwise instead of trying to intercept me by switching to counterclockwise.

When I was going for those last three stars, I'm really glad the blue Toxo kept moving up instead of down.

The red Toxo was hanging around the top middle gap, so I decided to move over a few tiles to be safe before going for the Big Star.

== End ==

That's the run! I hope this helps, let me know if there's anything you'd like more information on.
