You're welcome, I'm glad I could help!
There's a lot of things that are better n your version than his, though- like the screenshake not having a weird angle change and the ability to actually see your enemies, even when there's a lot of blood on the floor.
Maybe less speed, less health, or a smaller field of view would be better for the blue enemies- but they definitely deserve some "nerf".
I did, and don't remember it particularly? I think it was the one where I was at first overwhelemed, but gained control after a bit.
Oh, that would be interesting. Maybe there could be some stealth levels or something.
I'm not sure about the second one you mentioned, but I think you should definitely try it, polish it and evaluate it once it's done.
