Some guys on Twitch a couple nights ago decided to do a run of only the Horde Wave levels so I decided to try that as my first speedrun, and then I decided to do regular story mode too.

I just did a run and I came in about 7 minutes behind the record, even though I only had a minute more on 6-6.

I finally realized the record holders were somehow skipping the instruction screens. Just how do you do that?
