Post feedback for separation into subcategories, I think it's the best solution to keeping old gameplay styles and also allowing for the new trick outside of the glitch category.

I personally feel like separating them is the wrong choice. In my opinion it's a small glitch that is not game changing, like glitch category. Also absoluteing old runs is how speedruns work in my opinion. As more n more glitches are found in any game old optimized runs can be beaten strictly due to new glitches. I don't see any problem with getting the time lower with a glitch that doesn't really change the run.

My thought was that the focus goes away from drawing optimal vine paths since you skip it now, it becomes less about speed and accuracy and only about speed, which is a gameplay change in my opinion. Also I think that the only issue is that no vine skip is the default category, but once more vine skip runs are made, it can become the default or it can be mixed.

I would think its just nice to preserve the leader boards if nothing else

I can't say anything for easy runs with the glitch cause I haven't ran them yet but how you do medium with the glitch is basically identical to how you do it without the glitch (I've done 600 runs of it with the glitch)

It's not really free time save tho it requires execution and a lot of games find new glitches that you could view the same as "free timesave" but it's normall not separated.
