I personally don't think speedrunning is all about glitches. Some glitches break the game so much it makes running the game unfun. The categories and rules in Chained Together speedrunning community are fine and fun.

If we have category for all different ways to play the game it adds more work to mods who are not getting paid and not all mods run all categories. Every time run is submitted it needs someone to verify it. I feel like current rules and categories are fine. Only thing I would change is that game sounds should be required to make it easier to spot possible spliced runs, but I'm fine with current rules as long as I don't have to verify runs. :D
