Actually, those zips don't warp Keen inside the ceiling - instead, they warp him below the bottom of the level.
As I understand it, IBT refers to riding bullets upward; pogoing off bullets in midair is just standard bullet collision abuse.

The NES page already has many worse games than Air on it. The vast majority of these movies would greatly improve just about any page that's lucky enough to be graced by their presence.

I'd gladly share tales of strife and the blinding fury of a thousand suns, but the executive summary is that no revision of mednafen-rr can be built on Linux.
Kiss your PC-FX TASes goodbye, gentlemen.

The goals don't make sense to me. Collecting all instruments and then proceeding to enter the Egg without using them seems pointless.
The point of a run like this is to show off glitches that a straight speedrun wouldn't feature; I don't think the goals used are optimal to that end. As such, I'm voting No.

Version 1.4 features a glitch that allows Keen to skip all keystones in the final level without using IBT. This could be useful in a 100% run that forgoes some or all forms of bullet collision abuse.
Version 1.0 features numerous clipping errors that were fixed in later releases; it is definitely the version of choice for glitched runs.
For a low-glitch run, defining the goals is tricky. IBT isn't the only way to abuse bullet collision; the rest aren't quite as game-breaking, but they do make enormous time savings possible.

I've always wanted to do a playaround two-player arcade run with mouse input for Player 2 and keyboard input for Player 1. Too bad JPC-RR doesn't run Tyrian and that Hourglass doesn't support mouse input.
I don't like max% destroyed as a goal; the game has a ton of weapons to show off and in Arcade modes, you can already get Zica Laser and Constant Laser on a secret level accessible from the first level.
The official v2.1 data files have several boring glitches; most notably, the Charge Beam bug that can be used to gain orbiting balls of destruction much like the ones you get on that one Asteroid level, except that they destroy almost everything instantly. The data files provided on the OpenTyrian site don't feature this glitch.
Also, the very highest difficulties can't be accessed without using a predetermined/modified save; see OpenTyrian source for details.

She runs in JPC-RR. She's real slow (about 1/8th of realtime), but she runs alright.
The Internet doesn't hold too much information on this beauty, so things like differences between the various versions (1.0, 1.1 and 1.2; 2.x are the Windows port) are largely unknown.
The game scrolls somewhat slowly, so it might not be the most entertaining game choice on the planet. Howewer, playing on the hardest difficulty and destroying everything could still be interesting.
I'm currently using v1.0 of the full version; the boot movie can be located here.

If you don't finish the secret level by breaking the fuse, you won't get the best ending. I'd consider reaching the best ending to be an essential part of 100% completition.
Playing the level "normally" and then finishing by breaking the fuse is really hard to justify; I don't find the secret level entertaining enough for that to be an option. Check out the level layout yourself here.
EDIT: I'll also address franpa's woes about versions. The published glitched Keen 5 run uses the latest version because the feature/bug that allows warping to the secret level doesn't exist in previous versions. The improvement will also do so.
In the case of Keen 4, there aren't really any speedrun-relevant differences to speak of; v1.0 was used because it was the first one I happened to download.
For Keen 6: v1.0 has a lot more clipping errors than other versions, so it'll probably be the version of choice.
EDIT: THE FINAL EDIT: Found a way to manipulate the Shikadi Master. Sub-2:10 (with longer loading times than the published run and ending input after entering nick for high score screen) is the goal, and it seems possible. Too bad we may have to redo fucking everything.

The Shikadi Master is very unpredictable. In this POS (enters nick for the high score screen, ends input at 2:12.096), his malevolence costs about three seconds. As such, the entirety of QED will probably need to be redone.
EDIT: It seems that Volte-Faces, Shockshunds and the Shikadi Master all share a common property: not being manipulatable by delaying level entry and firing the Neural Stunner. As such, the three lost seconds are probably here to stay. The last few seconds in the v0 are very unoptimal since it was rushed out to get an estimate of the probable final time. Also, I'll be gone for a while, so don't stay tuned.

The glitched any% has been started and memory addresses have been found. Also, being rocked to the bone is more enjoyable than expected. Good times.
100% would seem to be less frustrating to TAS than in Keen 4 since there are no pesky oracles that can cost seconds and be hell to manipulate. There's also more variety between the any% and the 100%. Using the death flag glitch wouldn't seem be too entertaining in a 100% run, so I'm against using it.
Also, I'm using different emulator settings than Grunt, so the boot and loading times will be longer. Measuring the actual improvements is simple enough, so this won't be a problem.

Score was completely disregarded throughout the run. I didn't even notice the donuts when redoing PoGA for the umpteenth time.
Improving the Keen 5 glitched any% is what I'm currently planning. I might take a look at the first trilogy sometime in the future and if I'm going to do any of them, it'll probably be Marooned on Mars.
Keen Dreams never pleased me too much; the lack of a pogo stick makes both playing and TASing the game a chore.
The Berkeloid positioning achieved is indeed quite unlikely. When testing if the route was even possible by hanging from the ledge and letting the emulator run freely, the Berkeloid behaved as desired after around 80 seconds had passed.
I was extremely lucky when manipulating the Isle of Fire - optimal Berkeloid behaviour and excellent Oracle positioning was achieved with minimal delay.

The pyramids have now been redone. In the slower run, I had an optimal oracle positioning roll in the Pyramid of Darkness — no such luck this time around.
PoGA is slightly faster and PoD is more than slightly slower, both due to oracle positioning which I manipulated to the best of my ability. As such, I'm now a little less than a second ahead of the old run.
Edit: Crystalus is now done. Due to the Continuous Vertical Pogo (which is also used in the new Miragia) being figured out, gobs of time are saved and everything looks extremely fabulous. Unfortunately, the trick only seems to work on static platforms. Oracle positioning is less than ideal, but delaying level entry for superior oracle positioning resulted in horrible enemy positioning that prevented several cornerboosts.
Final Edit: The Cave of the Descendents and the The Perilous Pit are now done. Both look extremely fabulous with good and near-optimal oracle positioning, respectively. The The Perilous Pit features a new shortcut that enables reaching the Oracle door within a single elevator cycle.

Even if the DAR is correct, the MKV header will contain bonky values. While they may not be harmful, they look fugly and are just plain wrong.
I'll post the proper workaround here for those who might have missed it:

Lifewater Oasis has now been redone. The Isle of Fire jump turned out to be possible — I don't know what I was smoking.
Pyramids should be redone Soon™ with PoGA optimization being all but useless thanks to the shortcut. Maybe I'll try to find something entertaining to do in the upper part of the level.
Edit: The Pyramid of Darkness has now been redone.
Another edit: it appears that oracle positioning is random. As such, we're now redoing everything.
Yet another edit: Miragia improvements implemented, Oasis redone with very good oracle positioning rolls. EDIT: The improvements save around a second.

The current draft now completes Miragia, Oasis, PoD and PoGA.
It is almost 15 seconds faster than the old WIP because of a new shortcut in PoGA discovered by Cosmo, superior optimization, reduced rampant stupidity, and greater :effort:.
Grab the encode here. Poke me on #tasvideos for the most recent draft.

Cool story, bro. Care to cite any sources for this? Last I checked, pretty much every group that isn't a complete joke or using shareraws uses 10-bit in their primary (and usually only) release.

Read the news item about it on the front page. Then get the second WIP, now with 120% more Crystalus. If you desire the movie file, come slap me on #tasvideos.
Also, I'll be attempting to hex out the trainwreck at around 4:30 when I recover from post-slowdown stress disorder.

That is indeed the case. I hadn't done adequate testing at the time of writing the post.
I don't have strong enough insults to convey how I feel about the The Perilous Pit.
