I figured this would be a fun game to route and speedrun due to how open and interconnected the world is. Gave it a try and got a 7:14. Here's a video:
Note that the most important thing with this route is to hit the moving platform cycle at 2:56. If you miss it, it adds a lot of time to wait for the next cycle.Would love to see anyone else give this a try. I'm sure there's a better route than the one I took. You can get 10 spirits without any upgrades, so it's possible to get both the double jump and the sword on your first back to the hub. Might be a good route if you can figure it out.
Thanks again Warkus for making an awesome game!
