The goal of this category is: Collect all gold in every level in order. This category is for normal mode and perfect mode. Easy mode doesn't have gold. Cores are not required (normal mode). If you don't collect every gold bar in the bonus level you have to play that level again. Time starts when selecting 1-1 Time ends after you defeat the final boss at the fade out of the points screen.
I plan on running this soon but I think it should be a little different. You must play on perfect mode (This makes collecting every core a requirement). I think the player should start with no levels complete. This would mean you can only skip a level if you have already beaten it with all gold (!). Run ends when every level has !! (perfect score in not required) and you have beaten 3-Boss.
