This game is very cool, i really enjoyed it, and i think the interpretation of you being "in the shadows" is a very clever way to use the shadows theme, and it's executed very wonderfully here!
but i do have one complain, and that is the game feel of the platforming...yeah, it's good, but in my opinion it is too floaty, this complain can be ignored tho as it is more or so a personal preference
this game gets a wowie/10
