- Fixed a softlock when entering a room where you are blown upwards by wind, without dashing.

From Toby: 10 years ago I made a song that sounded like this. It's called "The Sunset of 7 Suns." This is the hope for Chapter 5 from 10 years ago.

--> Don't sweat the difficulty. As long as you keep trying, you'll get it eventually. --> By the way, we put a lot of effort into making the lyrics work, but they're more or less impossible to read while you're playing...
