^ this website is completely inaccurate in all of its conversions. My best advice is to download VirtualDub, a free program. The main UI has a frame counter at the bottom and it's very simple to cut the video down to just frame one of gameplay to the first frame of completion. I can even make a simple tutorial if necessary.

Found this over a year ago and it was said to be cheating so a full community discussion was never held. Trick involves beating a level then pressing escape and restarting before the level transition happens so it takes place as soon as you start level 1. Thoughts?
