I am currently 47th place on the Any% Leaderboards and wanted to improve my time. I saw that my best time improvement is in Sandbox 2 which I am about 5 seconds behind compared to the 1:59. So, I re-watched sirtymoo's "How to beat Karlson in under 2 Minutes" and I am trying to learn the trick where you use the shotgun and skip the entire level. I have gotten it maybe twice with one of them being slower than my shotgunless route. If anyone has a tutorial for what I am referring to that would be greatly appreciated.
