Shade is gripping, creepy, and creative.
However, it gets repetitive after a while. To an extent, this helps build up the suspenseful environment because the actions that you performed a few turns ago don't work anymore. Everything goes more and more wrong... but I feel like the game could have been trimmed down a little in this respect.
I also found that the ending was a little bit anti-climatic. It was almost like the author was trying too hard to be profound and it ultimately became meaningless.
