I also had the cursor problem (web version).
I remember when I previously played this, I said something about the ominous song, it brings a nice and serious atmosphere, but the enemies saying "ouch" is more on the funny side. I'd pick one of them, so the mood is clear.
These energy walls and computers are bringing a bit of what Perfect Dark used to have.
Maybe a game mode where you have to survive waves of enemies while having limited ammo?
