lol I'll assume you mean unintended glitches, and to answer that...not really

Once you've run this game for a long enough time, there aren't many glitches that happen where/when you don't expect them to, the game is surprisingly consistent in its glitches and it makes speedrunning this game viable.

Let me give you an example, casually you would never know that entering the final loop of wave ocean on the right side of the boost panel will send you careening off the edge instead of into the goal ring which kills you. That is a glitch, the boost pad should take you to the ring no matter where you enter it (and it sucks if you get caught by it) but it is easily avoidable. If you have that knowledge from previous runs and instead enter on the left of the loop, you will be fine and finish the stage normally.

There are tons more examples I could give you in every stage but the point is that although '06 is glitchy, most of the time random glitches don't happen to you in a speedrun, its very consistently glitchy that way.

Hope that helped!
