A bit late to the party, but I didn't think someone would ever attempt that back in 2017. Good job !

1-3 Insane-extreme demons ? In speedrunning ? Even if you are really good at the game, it would take too much time to complete. I know there are 10hours speedruns (and even more) for some games, but in this case, it would be really annoying to try and retry an extreme demons speedrun if you fail (to get the WR for example).

Edit : This category won't be affordable for everyone. A lot of players can't even beat an insane demon.

Good idea for a speedrun category. The only problem is that speedhack makes the songs delayed. That triggers me ^^ EDIT : Ok, actually I just fixed songs with Audacity.
