I am just going to list all my questions in a bulleted list.
•is there any rules on what cookies are allowed?
• is there a specific level/star requirement? 
•does a run have to start from the beginning of the game? 
•how exactly should a run be timed?
•does a run only need to be the boss fights, or should it have all the stages in it?
•when should a run be considered "dead"?
these are my only questions for now, but more might arise when I actually try the run.
