Doom SIGIL in VR - E5M2 (QuestZDoom)

I'm attempting to beat Doom: Sigil (v1.21) on the Meta Quest 2, played through QuestZDoom on the Ultra Violence difficulty.

Again, I'm going for 100% kills and 100% secrets; all maps from a pistol start; no saves.

Mods: Alternative Vanilla 3D Weapons; Customized MIDI soundfont (using Merlin, Chorium, Roland, and self-made samples).

The level music is from the James Paddock soundtrack; the Intermission music is from the Buckethead soundtrack.
