Emulated on RetroArch (Beetle PSX HW), with Quake II (PS1) rule's configuration, shown before and after the run.

24 tries until I managed to do a full run. I was so pissed that I couldn't manage to get past mission 1 that, once I did, I made mistakes everywhere else, getting stuck on every single door possible. Sub 30 is definetely possible, although there's so much RNG involved to not die on the first 2 missions that it ends up being a pain to even dare to grind this one out.

Times Mission 1 - 4:14 (4:14) Mission 2 - 13:23 (9:09) Mission 3 - 21:33 (8:09) Mission 4 - 28:00 (6:27) Mission 5 - 30:39 (2:39)
