bad idea for a speedrun category:
text%, where you have to get the game to display every possible textbox it can before completing it
BreakTheGame%: quickest crash. Time is subtracted for more interesting crash screens, and if you can get it to hardlock and then start playing Flappy Bird, you've gone into negatives.
and yes, this includes error messages if they are possible to see within the other bounds of the category (glitchless text% would probably not need any error messages, but glitched would include things like "THIS MESSAGE SHOULD NOT APPEAR")
