World 4x1. We took a break after beating world 3 and then picked up here. The stereo sound is messed up at the beginning, but it goes back to normal after a couple minutes. I guess I fixed it?
World 6x2. Okay, this might be confusing. At the end of this video, we accidentally find a warp zone to world 8. However, the next videos posted won't be in world 8. The videos will go straight through the rest of world 6 and then world 7.
World 6x3. Okay, now we're watching videos that are from the second recording session. We're all better at playing the game, which makes it much harder to make progress.
World 8x1. We're back onto the first recording session now. The 'skill' you saw back in world 7 is just about gone. At this point in recording, we were about 4 hours in and getting pretty tired.
