Washout Spire is a visually stunning game. The platforming mechanics are really fun as well. If I had any design critiques it would be that sometimes you have to do several hard/tedious platforming tricks in a row before a checkpoint. Most of the time that's fun, but there were a few occasions where I couldn't see a section long enough to figure out how to complete it. I plan on doing those sections again with invincibility to learn them, but it's something to keep in mind.
The only other comment I have is I think some amount of "coyote time" when jumping off of walls would have gone a long way. A lot of my deaths where because I pressed a direction key a split second before pressing the jump key, causing me to fall to my death. A smidge of coyote time when jumping off of the walls would fix this. It's a small thing really.
Overall, absolutely amazing game. I'm looking forward to learning all the chapters in the coming weeks.
