Thanks for the playthrough video and thoughts!
You are spot-on with the Celeste comparison, I love that game, and kind of realized the similarity after adding the "2 dashes" state. I'm definitely planning on doing the "touch this to get your dash back" thing, but I figure I'll have to make them pretty big considering how hard it is to be super precise with the movement.
I tend to make platforming stuff way too hard, so I really needed to watch someone playtest this to see how quickly they grasp the mechanics, when I can expect them to be ready to learn the down-bounce and other intricacies, etc. So this was super helpful, thanks.
Also, there are already two secrets if you're really tight with your movement, one in Level 3 and a -very- hard one in Level 1 if you wanted to look for them ;)
