So the category is just Any%, no mention of glitches. But because basehaxx exists, I think there is possibility to use it in a similar way to credits warp or something like that for a faster run.

Is this true, or am I mistaken? The rules don't specify. I don't plan on running this game, this is more for anybody who does.

When something abusable actually becomes exploitable, separating categories will be happening. Until then, there is no real need to mention anything.

If a major glitch is found that actually cuts the time of the run significantly, obviously Glitchless rules will be created.
