I often wonder if you have notes taken or a cheat sheet of sorts with every enemy and secret marked on it, or if it just comes down to replaying the levels repeatedly until you develop perfect muscle memory The car ride transition level was also really cool, it's interesting to see how modders utilize the primitive engine in creative ways :D
I do practice runs for these levels before recording plus it helps too I've played this mod several times in the past. I too thought the car ride was a neat touch. It reminds me of the Bloody Pulp Fiction custom episode. In that mod, there are several level transitions where Caleb drives a car. I may want to come back to that mod too when I get the chance.
