Here are my demos:
I played on Normal but could have played on Hard. I didn't use but did find lightning guns in secrets. Also didn't use the rocket launcher. I was just having too much fun with the tripple boomstick and the nailgun.
The reason I found many of the secrets was because I didn't see at first where to find the gold key, so I went exploring. I liked the exploring though, stuff to find everywhere and feel good about it.
I really had fun at the end, backed up against the exit teleporter and NOT letting go of the fire button. I finally survived with 20-30 health and no armor.
There is no need to go over the things that were pulled of exquisitely as I couldn't do it better. Thank you very much for making this level, I had a blast playing it.
I wonder if the nordic runes on the blade read: ”Grendel's Slayer of Deities“, or anything at all. I'll be right back when I find something.
