The atmosphere and art here are great, as well as the sound effects. The concept of the game is not quite as original enough the carry the game on it's own, but it's kind of cool. The level design is really hit and miss here, as at times I was really impressed with the clever way you thought to you use the mirror, but the platforming part of it ranged from mediocre to boring. Pro Tip: Even in a puzzle platformer you should never have incredibly slow moving hazards that are unnavoidable, kill in one hit and force the player to travel incredibly slowly through the level. More than a few times I was nearing the end of a level when I was killed and forced to start crawling through again, and it wasn't any fun.
Overall this was okay though. The art in particularly is brilliant, atmosphere is great and the game feels fine. The bad platforming pretty much ruins the later half of the game.
