DOOM (2016) Level 7 Ultra-Nightmare! (All Secrets Found)

My first time beating the Ultra-Nightmare difficulty.
In the first levels I played normally but when I get farther I started to feel nervous because of the deaths, So in the advanced levels You can see me playing a bit uneasy and aiming badly too.
Also the lag while I was recording was terrible too.
I found all the secrets including all marine toys and I completed all runes challenges but I failed some rune challenges.
