Estimated around 3 hours 6 minutes to beat. Maybe slightly longer. I lost the footage of the final stage being beaten in my legit run, so I edited in the footage from my practice session. It still shows those stages being beaten so doesnt affect that. The difference is that you have to beat the final two stages back to back with the lives given. I did that but lost that specific footage.
Unedited except for the semi final stage which took over 2 hours to beat. I edited out the losses for that section since it was excessive. Also edited together the last two stages done successfully in my practice session since I lost the legit footage. Looks the same in a video though. Despite its title you wont be poppin woodies on the semi final stage.
