So I did manage to beat Lost Levels, surprisingly, but I haven't uploaded the video to Youtube yet so I can't really prove it... Will it be too late to link the video when it's been uploaded?
EDIT: DONE. NEVER AGAIN.
...The Super Mario Bros. theme will forever haunt me.
You the man. Congrats!
Update on mine...well, I forgot that there's a certain level that is required to beat that needed a certain amount of star coins. Since I was trying to beat it as fast as possible, I didn't really try to get the coins. When I reached that point I lost the will to try. It's too late anyway lol. Why did 3D Land make star coins pretty significant to the main playthrough? Pretty stupid.
