@SlowMotionKarma That's the gist of it, yeah. Shooting down enemies nets you time, getting hit drains it. Some enemies and obstacles are one kit kills, but those are fairly rare occasions. But there's enough opportunity of swimming through swarms of bullets that if you're sloppy, you won't survive, yet you don;t need to avoid every single bullet to avoid death. The challenge is certainly there, and enough to feel like you're really on your toes, but it's not abusive.
