Description:
Another one.

Thanks to almostmatt1 and rockygaming4725 for pointing out the off axis/diagonal wall here. Spent quite a bit of time trying to get it to work, but once I understood what I had to do it didn't take too long.

Could have used a rocket by the exit to get past the door extending out into the void quicker if I had saved one and had conserved enough health. Also several other things that could have been a bit faster, but the IL non-TAS record is 0:59, or 0:30 in the 9:42 D2All TAS, so it's much faster. With a plasma rifle at the start from a D2All you could save even more time.

The reason you can go through the wall here is because a wall is slightly tilted away from the x-axis, but because the angle off the corner is just barely larger than 90 degrees it means I need quite a bit of momentum in both directions to get it to work, hence the double rocket boost, though it might be possible with only 1. So together with some very precise position on the frame before I go through the wall and high momentum I get the extra speed needed (because of slide movement against the wall) to go above the max speed limit of 30 units per tic for 1 frame and go through the wall. Doomguy is 32x32 units so at least 32 unit per tic is needed. Technical description can be found here under the void glide section: https://www.doomworld.com/forum/topic/87199-the-doom-movement-bible/

Finding a way to do it non-TAS might be impossible, even if it is possible it would probably take too long to set up to save time, but who knows.
