The run is definitely sloppy in spots, but this level was very difficult to get a completion.

Most of the run is straightforward, but you can have some of your jumps blocked by enemies you can't see.

Hardest part for me was the pillar climb towards the ending. Am glad I could get it first try.

The final stretch to the exit door is not easy either. This run I tried hugging left side of final elevator and shooting before going up and it seemed to help get the big guys out of the way a bit..
