For glitchless, if the rocks are already exploded or they fell in a way that you can go through would it be disqualified?

no, that's why we reset until we have rocks that are passable

I have another question, considering we can "continue when rocks are passable", isn't that technically still considered help from other players? And even if it isn't, could I not just remove the rocks myself and then start a new fresh run?

gekki stop exposing these very exploitable strats, i need my wr!!!
