I'm a minimalistic writer/gamer and this game just tugged my minimalistic heart strings. It plays as a puzzle-platform, yet unique in that you use a shadow of "yourself" as a tool to pass obstacles. The story is simple yet you also simply fall in love with it.
It's well-made as a puzzle-platformer. However, I also enjoyed the way the story and emotion were tied in to the game and parallel to level design. Only problem I foresee is if people do not read the text at the beginning or end of the game... These people miss out on the emotional aspect..
Cool! Only played into a bit just now, but it reminded me of Braid which if you haven't tried you would probably really like hunch.com/item/hn_3590484/braid/ (available on Steam among other things)
