Gunslinga Corridor 100% (Spam Demon)

This level was painful, it was the next extreme that was randomly generated, and I already had 64 on it from a long time ago but dropped it because I couldn't spam well enough. Since I'm on shift key now it was doable, but I still didn't like it and died past 80+ over 10 times and died to 93.
