It's been almost 2 years since anything has been posted here, and I am wanting to keep this discussion alive since I've created TAS'es for this game "all tracks in 2:19:48.15"
I am creating a new TAS that hopefully crushes that time by about 8 1/2 mins maybe 9 mins.
I am right now trying to solve an issue currently residing on Wall Glitches, namely on Aswan, the 2nd track in Eygpt that I am currently on. However, the issue lies with being able to make the car hit the Grey wall, get stuck, not hit the rock that is semi-connected to the wall, and finish the race within 9-ish, to 10 seconds overall. Doing this would make the run almost 3 mins faster than the current published TAS.
There are other tracks that I would like to discuss as well, but 1 track at a time for now, so it's not confusing and complicated.
Here is a Gyazo GIF that I took trying to get a visualization of what I'm trying to accomplish:

Here is the password with the current upgrades being used if anybody wants to help test this: J26P G6YD QPDP 28(HM ?87NN (Password is for anybody that wants to use it, no passwords will be used in this TAS I'm making).
