There are a couple of things I should mention: At minute 47.29 I evaded the scene because of my habit of jumping all the time and at minute 58.58 I bugged my secondary weapon. At first it looked like I was going to get infinite ammo or something but it was the opposite, I couldn't use the secondary weapon and for the rest of the game I could only use one. I hope it still counts as glitchless or I will have to do it again.

Does it still count as glitchless?
