I would have posted it on YouTube, otherwise speedrun retired again on twitch.
Personally, I would look at such speed runs, where there will be no: mind control systems, clone-compartment, hacking system and other things)
Suzu Low%. The character is very fast, kills even bosses with 1 hit if you kill a mob first. In general, it would be interesting to see this category.
Is it possible to make a high% category with permission to use item and shrines? At first I think one category is enough, with the name of any high% character (Any character). Anyway, only a few characters change bosses in the game - Cadence, Melody, Aria, Nocturna. Yes, it's random, collect the desired item, but in all zones mode, all items are open. Speedrun will also depend on the randomness and your knowledge, timings, when you need or do not need to buy items. There was also an idea to add a separate header between the Platform and the date. Character.
