I really liked this game! Very interesting mechanic and fun to play. I liked the platforming a lot, and it was cool to see it turn into a sort of top-down but still platformer game in the shadows.
I really liked the art and the music too. Very good and fitting!
I think my only feedback would be it was hard to tell where some of the shadow areas began and ended. Other than that, it was very fun! Great job!! :D
