This idea is really fantastic. The green light/solid shadow mechanic in particular is incredibly innovative, I don't think I've seen anything like it, awesome job!
I wish there was a way to scroll through the level and see what lights were coming up; it felt like for some of the longer levels it would take me a few tries to just see that there was a light coming up that I needed to click. It also felt like the double jump was a little unresponsive, but that might just be me being bad.
There's a lot of really great design here. I really like the mechanic of turning a green light off, and then immediately turning it back on once the shadows are beneficial to you. Excellent work!
