First sub 2:30! I was having network issues during this stream, which means I really need to start recording these...

There's just 1 more time save that I know of, which is in 1-3 Caverns there is a very tiny window of opportunity to jump up the "stairs" instead of walking into the wall. Would save an additional half second or more.
