The RPG mechanics (mostly because of scaling) and combat blow ass, but it's fun to speed run. I highly recommend anyone who's interested try to learn Any%, because it's such a short and easy run. The bulk of the run is actually just getting out of the tutorial.

You learn 1 trick to pass through walls and basically just walk to a trigger that sends you to the end of the game. You could probably learn it and get good at it in about a half hour. It's probably one of the easiest games to get a respectable position on the speedrun.com leaderboards.
