Just GR-18 doing his things.

While GR-18 is sprinting, jumps gain 1 extra tile of height. This allows GR-18 to reach a total of 5 tiles high.

(Fun Names, Alternate Names)
Normally when GR-18 changes lateral direction changes, sprint is lost. However, changing directions while in mid-air preserves the sprint. While sprinting, jump and move in the opposite direction of the current run direction to preserve sprint in the opposite direction.

(7 Makes 8, Impossible Sprint)
Normally a sprint requires 8 tiles to activate. If you land just on the edge of a 7 length tileset GR-18 can gain sprint by the end. This is especially useful if you’re on a 7 tile length and gain this by jumping off and looping back on.

The box, the tool, the goal!

(Package Bop)

Throw the package at enemies like a bully! Pushing them away or into the pit! This also breaks enemy attack actions, like a Swoopadoop’s swoop or a Flipwip’s tongue-out.

Throw the package at a jem to collect it. Combine this with various jumps to collect out of reach jems. Since the package can pass through objects that kill GR-18, jem fishing can also be used to grab jems behind hazards like Burny Whirlers. Similarly, the package can be used to grab jems that would be disabled by an eye switch. Since the package respawns, it can also be tossed at a jem and into the void to be picked up again at the spawn.

GR-18 can stand on the Package or a Throw Block and jump from it to reach 1 tile higher (5 total). The crate or package can also be picked up with a down grab immediately after jumping to bring it with GR-18.

(PJP)
While the package is on a Spikeatron, GR-18 can safely stand on the package. Starting from that state, perform a Package Jump then throw the package down at the end of the jump. GR-18 can navigate a floor of Spikeatrons by repeating this technique. This also works with a Throw Block.

Tech demo level : 2njlkjk | "Package Jump Panic" by BscotchSeth @bscotch101[lvlhd.co]

Throw the Package upwards. While the package is in the air, press jump to leave the ground and press jump again just as GR-18’s feet pass the top of the Package. This allows GR-18 to reach a height of 9 tiles. Immediately after the jump off the Package, perform a down grab to take the package with GR-18. This can also be performed with a Throw Block.

(Improbable Package Hop)
Throw the package down on an enemy and then perform a mid-air package jump. This allows GR-18 to traverse rows of cromblers or ‘bounce’ off a single crombler.

(Ceiling Sleep)
A 3 high and 2 wide Spiketron with a 1 ceiling gap above can be cleared by throwing the package down while traversing over it.

When standing just under the edge of a ceiling and making a throw, the package is thrown an extended distance.

Sometimes, a normal Super Jump won't help GR-18 ascend high enough because of some Obstacle! So why not be creative and use the Wall to help to reach the peak?! Sprint jump near a wall, throw the package against the wall while ascending, then jump again on the package after the package bounces off the wall.

No Ground but got a Ceiling to work with? Fear not! With this awesome Technique GR-18 will climb even the worst Cliffs! As GR-18 approaches a ceiling from a jump, toss the package upwards, quickly turn back to line up with the rebounding package, then jump again on the package after the package bounces off the ceiling.

(Infinite Super Jump 2, Flantastic Flight, ISJ 2: Back from the Dead)
The Double Super Jump technique can be chained by grabbing the jumped off packages. This allows for infinite vertical or diagonal distances.

Climb, hang and slide to coolness.

(Tow Slide)
When contacting a wall with vertical momentum from a jump, hold jump to retain that momentum up against the wall. This allows slipping past 1 tile width gaps by pressing against the wall. This technique does not seem to work from non-jumping momentum sources (e.g. Sky Wigglers). From a regular jump this technique can be used between walls to bypass a 3 high spiketron wall.

Tech demo level : jvp1p6s | "Tiptow Slide Up" by PureKnickers @ref0kg[lvlhd.co]

(Bush slide)
After contacting a wall and beginning the slide animation, use tiptow’s special ability to turn into a bush while still sliding on the wall. Tech will not work if GR-18 turns into a bush before sliding.

Charge, bash and glare to victory.

The Waylay charge can destroy bullets, even when they would normally have priority over GR-18.

Charging along the ground prevents GR-18 from contacting hazards on the same level. GR-18 still needs to finish the charge on a standable block.

Tech demo level : jsgn9tc | "Rough Waylay Tutorial!" by Intuition @g3204t [lvlhd.co](first challenge)

Charging while sprinting increases the Waylay ground charge distance to allow clearance of 12 tiles.

GR-18 will NOT rebound up and backwards if you smash into a wall/brick/bristle block that is 6 (5.5) tiles away when making a ground charge!

Tech demo level : jsgn9tc | "Rough Waylay Tutorial!" by Intuition @g3204t[lvlhd.co] (second challenge)

Air charging through a power-up purge gate or new power-up causes cancels the Waylay charge, but keeps the momentum. The result is a huge maintaining of speed and jump distance without the slowdown of the Waylay charge deceleration. (needed : jump distance/height)

Perform a diagonal ariel charge into a wall. GR-18 will bounce back up to 3 tiles from the contact point. This can be used to access gaps up to 9 tiles high.

(Coyote Charge Jump)
Charging and then jumping from just over the edge allows GR-18 to make a lengthy jump. (needed : jump distance/height)

Tech demo level : lvn0dcp | "Waylay Speed Jump Test" by SleepyDoof @zchv6z[lvlhd.co]

(Waylay Coyote-Punch)
Stand beside a wall, dash into it and press jump as GR-18 rises from the rebound. GR-18 will perform a coyote jump off the rebound. Even though you "stood" beside the wall, GR-18 can jump as high as if you were sprinting (5 tiles)! This can be performed from afar, however a closer start makes the jump timing easier.

GR-18 can make a frame perfect jump when charging into a wall that’s at most 3 tiles (run-dash) or 9 tiles (sprint dash) away. Charge into a wall and press jump just as GR-18 touches the wall.

Zip, zap, zoop

Zipping preserves any vertical momentum, allowing GR-18 to reach platforms above the final zip height. This applies to momentum from jumping, bombs, wigglers or any vertical momentum.

A Zip-Up can be performed from a standing position by jumping and zipping simultaneously. This allows GR-18 to zip from a spot with no clearance and still reach regular jump height after the zip.

Zipper’s teleport can get you into spaces you might not expect, such as between spiketrons and cromblers

If a zip is buffered during a respawn at a Budd-E the following zip can be shortened around spiketrons. The zip will treat spiketrons like walls due to being invincible. A jump can also be buffered with the Blip Zip.

Things, stuff, and throwables.

While in the air, throw any item downwards. This provides GR-18 with an extra tile of height.

Tech demo video : Levelhead Item Hopping Example - TripleB36 (Opening section)
Entry Credit : TripleB36[www.bscotch.net]

Item hopping allows GR-18 to traverse a row of Spiketrons using throwable items. While holding down and a lateral direction, repeatedly press grab. GR-18 will alternate throwing the item down and picking the item up. The kick boost from throwing the item down prevents GR-18 from touching the ground. This tech can be done with any item that rolls.

Lose control accurately.

While sprinting, jump as you hit the bumper. GR-18 will launch about 16 tiles upwards.

Flying for robots without wings or jetpacks.

Flyblocks transfer their momentum to GR-18’s jump, providing higher and further jumps. Jumps can reach a height of 8.

Wiggle through the molecules.

Hold down while on a wiggler to descend down the wiggler. Once stable on the wiggler, hold down-right or down-left to walk along the wiggler.

Hold down on a sky wiggler until GR-18’s feet are touching the wiggler, then release. The wiggler will launch GR-18 8 tiles upwards.

Tech demo level : 1ptzc9k | "No Down Sky Wiggler Jump" by PureKnickers @ref0kg[lvlhd.co]

Hold down on a sky wiggler until GR-18’s feet are touching the wiggler and then press jump to launch GR-18 14 tiles upwards.

Tech demo level : 1ptzc9k | "No Down Sky Wiggler Jump" by PureKnickers @ref0kg[lvlhd.co]

Hold down on a sky wiggler until GR-18’s feet almost touch the wiggler, let go of all directions while pressing jump to launch GR-18 17 tiles upwards. The technique was successful if the jump sound and animation do not play.

Tech demo level : 1ptzc9k | "No Down Sky Wiggler Jump" by PureKnickers @ref0kg[lvlhd.co]

Without vertical momentum, enter a series of wigglers about 4 tiles above the wigglers to traverse the wigglers with minimal vertical movement. Entering at the peak of GR-18’s normal jump works for this tech.

(Secret Keeper Jump)
GR-18 can buffer his jump off Invisible Upside-Down Prizeblocks so that they stay invisible and unused!

Powered by GR-18

If a door closes on GR-18 and he is inside of the block, but only enough to be pushed out and not crushed, he can perform another jump off of the gate itself. A full jump can be made from the top of the gate, adding 2 tiles to whichever jump you can perform off the gate.

(Ledge Jumping)
Using the properties of the circular hazard hitbox, it is possible to stand GR-18 on the very edge of a solid block that has a Spiketron above it. This also applies to Spike Traps and Whizblades. This does not apply to 1x scale Cromblers (confirmation needed).

When destroying an enemy by landing on it, hold the jump button. GR-18 will ascend 4 tiles above the top of the enemy.

When destroying an enemy by landing on it, press the jump button immediately after destroying the enemy. GR-18 will ascend 5 tiles above the top of the enemy.

Mostly harmless floaties.


When holding a Blopsack with Waylay, GR-18 can ascend infinitely by using the aerial charge.

Telechompers

(Popjaw Pop)
GR-18 usually ‘pops’ up 1 tile after a medallion teleport. This can be increased to a height of 5 by pressing jump just as the teleportation activates.

Sometimes updates make tech obsolete or impossible. Here lies old tech. Many of the levels will still work since mechanic updates are often not retroactive to published levels.

Jumping straight up off of a toe slider followed by an ariel charge into a wall causes the rebound to extend 5 tiles away from the wall. Does not seem to be affected by toe slider speed.

^Patch 0.9.8^
You no longer decelerate if you are pressing a direction key that is the same direction as your inherited Xspeed from a treadmill or a platform. You will only decelerate the inherited speed if you push *against* it.

(Lizumi quirky behavior)
Lizumi usually always starts walking to the left. However, if GR-18 stands on the right side of any Lizumi and you pause the game. You'll notice that it "turns" towards GR-18. "Restart" the level now. The Lizumi that's supposed to walk to the left after "starting" the level - will now be going to the right! The same applies to reaching the Goal & restarting from there!

^Patch 0.14.?^
Enemies would sometimes start facing different directions depending on whether you restarted the level or were starting for the first time. This has been fixed, but will only be applied to levels published during or after this version.
