Boogie bot bug + ToA - mostly are disliked because. Its not even get used in most levels + its also easy to do the ToA and the bot bug Also there are many shortcuts with same tricks. Falling from up to bottom (Without stairs+designed path) it gets frustating for the creator who created the level.
SBB, Auto pilot and ToA are my favorite ToA is trick that if you miss it mostley of the time you have to reset the level, so if you try to make a difficult level this is your big shot
