Welcome! May your future ones be blessed by better grammar.
So, I played through VC SMB today. It took 44 minutes. My first death was in 4-2, because I miscalculated and wound up at the Warp Zone and waited for time to deplete so I could avoid using it. The first time I really died was in 7-1. Died three times in 8-3, and twice in 8-4, for a total of 9 deaths. I got plenty of coins to sustain me and only didn't get the reward 1-Up in 6-1. Yes, I have a video but I won't be uploading it anywhere because it's 44 minutes and 20 long, 87.3 MB, and has horrible audio: my birds never shut up throughout the whole thing and I was stupid enough to place the microphone by the rotating fan so it sounds like a continual lightning storm is going on.
