Just watched your vid for the first time, I missed it during the launch. Glad you had fun with it! You got some tough mutations unfortunately. 

I had a couple tips as well if you end up playing more. M opens the map and can help you navigate to the loot around the level more easily. There's always one item cache per level and usually 2-4 weapon spawns. Also you can hold two weapons, left control on keyboard switches to your second weapon and when picking up a new weapon it will swap whatever one you're holding.
