About the game and movie

Basic mechanics

Running

Billy has a run speed of 200 units per frame, I give this value as a scale for the speed tricks in this run.

Jumping

When jumping, you don't move for one frame, and when you land, you also don't move a frame, so jumping as little as possible is an important part of this run.

Attracting

With a press of the Z key, Billy will start to attract to metallic object, this is usually used to reach areas that "in theory" would be impossible to reach. Also, by staying in place, the attraction shield will increase in radius until a certain point.

Magnetic rails

Whenever you stop attracting to a rail, the speed you had the frame before ceasing attraction will be converted to your running speed. Rails usually make you go 300 units per frame, so if you were to stop attracting, you would move at 300 speed, which is faster than the regular speed. A weird quirk I found is that attracting to a rail becomes pretty much impossible at speeds higher than 600 because Billy stops attracting to them, but only sometimes for some reason.

Enemies

Throughout the stage, there are some pink enemies, but they can only be killed by using weapons or spike balls. Unfortunately, most of those are inaccessible without it being slower, so I'm forced to make some otherwise unnecessary jumps. A weird thing regarding jumping on them is that they only have collision detection directly in front of them, so you can jump through them pretty easily.

Looking up or down

By pressing the up and down arrows while on the ground, you can look either up or down, allowing you to see farther in the respective directions. It wouldn't save any time aside from maybe loading something earlier.

Tricks and glitches

Faster running

While running, you run at 200 units per frame, however, by unpressing and pressing the directional buttons, you can move faster, I always do this: Reach 200 of speed, unpress for a frame, hold for two frames, unpress for a frame and now I move at 234 unit per frame. This can only be done on the ground, doing it on the air will completely halt your momentum.

Ledge jump

When walking off ledges, you can jump in the air.

Double jump

By jumping the frame you land, Billy will jump while in his running animation, you can press the jump button to jump again. It's very simple, but it's one of the most widely used tricks in the run.

Box jump

When going upwards, Billy will always snap to the top of the metal boxes, this can be used to jump more quickly without losing time.

Corner boost

By jumping in the corner of a box, you will get pushed slightly forward and the box will be pushed slightly backwards.

Attraction jump

Whenever you stop attracting from a rail or metallic platform, you can jump again, this is used to climb high areas without slowing down.

Attraction speed

Now it's time to talk about the single most important glitch in the game. When you try to attract to a rail or a metallic platform, if Billy detects it, he will start moving towards it at an increasing speed, and remember how stopping attraction will convert your current speed into running speed? Well, this applies even when you haven't fully attracted to the rail, this means you can start moving at very high speeds without wasting much time. There is a caveat, which is that this attracting speed on rails has a variable cap that maximizes at 580 speed, but this only applies to rails, since for some reason, metallic platform don't have this limit, meaning you can practically go as fast as you want. The reason why this glitch is so useful is that it opens a branch of other glitches, so many in fact that it has its own segment.

Glitches derived from Attraction speed

Rail jam

In some parts of the rails, if Billy attracts to it, he will end up vibrating between two positions very close to each other, this isn't very useful, but it's actually used in the run.

Attraction disassociation

If you're going fast enough and start attracting to a rail behind you at the latest frame possible, you will still be in the attraction state with the same X speed you have without moving back. This can be used for many thing, it can be used to increase or decrease your height without losing any speed, allowing you to make some pretty absurd distances. However, touching a wall will make you start attracting back to the rail you were supposed to be attracting to. Also, I kinda lied in the Attraction speed section because all of the following glitches actually happen because of this trick, not Attraction speed. However, since you can only do Attraction disassociation at higher speeds, Attraction speed is absolutely necessary.

Floor clips

When in attraction disassociation and moving downwards, most of the time you will clip through thin floors, however, on rare ocasions, you can clip through thicker floors which has two possible outcomes. You either snap to the part below the floor and lose all your speed, or start moving horizontally at a rapidly increasing speed until you get out of the wall and lose all your speed again. The way your speed increases in the latter is interesting because you can either end up close to the wall or very far way from it, depending by how many units you moved in the last frame.

Wall clip

If you're going fast enough (above 900 units per frame) you will clip through every wall, including thicker walls (note that you will lose all your speed if your positioning ends up making you be inside the wall for more than 2 frames while running, which is why it only really works on thin walls).

Bound clip

The walls that block off the Out-of-Bounds have a weird property. If Billy's experiencing Attraction disassociation, you can clip through them, at any speed. If you stop attracting, Billy will snap to the closest position in bounds horizontally.

Warping

This is the strangest trick in the game. For some reason, if Billy's experiencing Attraction disassociation and touches something that damages him while in that state, he will warp the equivalent of the distance you spent on that state. For example, if you are in a disassociation state and move 10 frames forward at a speed of 400, you will then teleport 4000 units forward. This glitch only works sometimes for some reason, it seems to only work when moving upwards or sideways.

Unused tricks and glitches

Damage boost

When taking damage, Billy will be moving at 300 units per frame for a while, which is faster than the regular running speed. It wasn't used since getting a speed above 300 with Attraction speed is pretty trivial.

Box clip

When smashing a metal box against yourself close to a wall, you or the box can clip through the wall. It's very inconsistent and it wouldn't save time anywhere.

The nothing pusher

If you're walking against an enemy and that enemy dies while you're still pushing it, Billy will be moving in the pushing animation. You can't jump out of this action without stopping, so it's pretty much useless.

Ultimate floor clip

By executing a Bound clip and not stopping the attraction until a certain point, Billy will clip through the floor, softlocking the game. This is obviously very bad, unless you were actually trying to softlock the game.

Thanks

Special thanks to CasualPokePlayer for creating a script that allowed me to see how many units I moved every frame, even if the script wasn't explicitly made for this game. This run (and the run this script was made for) would be way worse if it wasn't for this script.

The future

I plan on doing an "all cheese" run, though it's going to take a long time, with a lot of routing and stuff.
