But: how does one level-up in Old School mode without turning the mode off? For example, to achieve "Warrior Princess", one must get a 30% bonus; on a lower level one has to beat a boss. Am I missing something?

Wicked, wicked game. Thanks.

Old school mode can get you some of the awards, but some require playing original classic/code red that involve bosses and revive targets.
