hehe Aglar, that is not the way we did it though!
You can skip alot, which is the reason we wanna do a new TAS and I want to be a part of it, and yes, we (me and Arva) have been doing these tests, doing the vine thing all over the place, but we are not TAS:ers so we need your help!
This trick allows you to gain loads of time in a Any% or Warpless TAS! Continue was used because you wanna have the first charactor selection screen, and as Aglar said, you can do this without a continue but that means you have to go to 1-2, kill birdo, warp back to 1-1 and warp your way to 1-3 without ever stepping into that level, that was what Andrew did. I think our way is gonna make a more awesome TAS, You are done with world 1 in like 40 seconds, lol!
SDA haven't decided on a verdict yet, Their current ruling is that the timing start when you enter the charactor selection screen, but if that could be used from a continue, we have to see!
