I really liked this game. There was a part where I noticed there was a sort-of double-jump, and thought it might have been a bug (wouldn't be the first jam game I've seen with a broken double jump). However, I shortly afterwards came across a screen that required it, and I realized that this game was more clever than I was giving it credit for.
I have two complaints: One: the sides of spikes hurt. That's less a complaint specifically about your game, as I know it's pervasive, but it's still a peeve of mine. And two: The final boss fight was extremely frustrating. Between the boss' attacks being highly RNG based (mostly with the speed) and the fact that the difficulty seemed to increase with time whether or not you're getting hits in made it feel rather unfair. The second hit in particular felt like a ton of RNG to me. Honestly, I feel that the boss fight needs retooling, but with that, this would be a perfect game. (EDIT also found a typo in the intro. It's "vertical", not "verticle". Fix that as well and it's perfect)
Also, I got 4/7, and now I want to see if I can find the rest. :)
