Sorry to bother you, but I have a question. If a run requires more than 1 level to be played, is it timed level by level (the way described in Rule-Set and Glitch List), or is the menue timed too? Maybe a stupid question, but thanx in advance.

what runs require more than 1 level to be played?

If you mean all achievements in category extension. it is by real time: From the first load. to the last achievement popup)
