First:

Apparently you can start boosting during the cut scene. This seems to happen if you mash boosts in the beginning of entering the level.

Secondly I have managed to start boosting when supposed to hit the mother ship before ROB has finished his dialogue. His textboxes are still visible but for some reason I have managed to interrupt the cut scene without knowing how. This has happened to me twice in Asteroid Field.

Anyone know anything about this or feel like helping me look into it?
