If you want to be pure good or bad, beat the nuteral levels untel the level right before Iron Jungle. Then if you want to be good be good in the level before Iron Jungle Be good, then good again. And do the same thing if you want to be pure dark, exept every time i said be good be bad. And that will easily take you to the last pure hero, and pure dark levels. For semi dark, and semi hero. Just be normal untel Iron Jungle and then be either good or bad, and that will take you to the semi dark, or the semi hero levels.
