So this is a skill that I was aware of, however I never really thought to use before in speedrunning. Air Jumping is jumping in mid air using an object. It is detailed a little in this steam post here: https://steamcommunity.com/sharedfiles/filedetails/?id=857064483 Meanwhile a short video showcasing the ability is shown here:

Initially I was unsure if this would be of any use at all for speedrunning as the oppertunity to use it is very limited and situational. In Halloween Hellrun speedruns in particular however I think this technique could potentially be used significantly. In the level Boneyard Blitz you can air jump off of the falling bones, alowing you to dodge a lot of obsticals throughout the level given that there are so many of them. Meanwhile in Sundown Slaughter as you are always invincible you can air jump off of the other dinos. Again this could be very helpful at saving time.

I haven't fully explored this yet, but the potential is there so I thought I'd share it :)

I've tried using this to my advantage for a while now, not so much to get an extra jump but to activate your boost. If you have boost available and hit something mid air it can activate giving you speed in the air,which is why I tend to have the "Meteor Storm" Cheat/Mod on when running any% categories in the off chance I get use out of it. I believe the game treats things in the air for a tiny moment as something you can stand on which is why I think this is possible (as well as being able to jump off of them), which also can lead to some interesting mechanics as such: The video is a run where I have "Freerun" mode activated and by holding "SHIFT" + "Y", you spam summon red dactyls to give you the ability to "Sky Walk" by running on them mid air. This tech is currently not accepted on the leader boards as "Freerun" mode essentially has no end like you may have noticed in the video, on the final level when I reach the haven, the level doesn't end, I just pause the game to stop the timer. It is not accepted on the leader boards because FruitNationalist and I could not come to an agreement on the matter but I figured I'd put this information out there to get the community's opinion. :)

Yeah I thought the Meteor storm idea was great for any% runs! I never really considered it myself before seeing your run. I always assumed that actually jumping off of them would tend to slow you down to an average speed though, which is why I initially thought it wouldn't be useful at all for any runs where the super speed is in play. That video is awesome though! It's a pretty hilarious strategy to look at but it works XD
