Tougher than leather soaked in year-old grease. Somehow if you stick to it, you'll see yourself grow tougher yourself. After 20 restarts I got my first achievement Beat a room without taking damage. After 50 deaths, I finally looked up a guide on how to strafe correctly. It's not about 'Git Good'. It's about 'Git Better'. Learn-adapt. Your reflexes will eventually catch up. Those glowing bullets will start to look dodge-able. Very thankful for this game. Might just get me to start playing FPS more.
