If your game crashes, you can continue (if you didn't select continue without saving), but the timer must continue while you re-enter the file after the crash.
Also, for any% there is an out of bounds trigger to the final level, which you can reach and beat the level (using several glitches). This technically doesn't finish the story, but it has been recognised as the end of the game for the purposes of any%.
Oh, that is very true. I think that Astronaughty launch in the final room is easier and I think it saves more time (not to mention all of the easier strats throughout the run)
Edit: I take this back in several ways. I think it is worth to do it in all chapters, and definitely not worth to do Astronaughty launch.
Can it be made so that the flag can be a region e.g. Greater London not just England or UK.
