This has actually been one of my favorite games for a long time. There are plenty of reasons for it too.
-8 bit graphics (I mean, come on, who doesn't like 8 bit graphics?)
-A sense of undeniable eeriness throughout the entirety of the game.
-The unfolding mystery as the game progresses
-The climactic ending
I wish it would have been longer, but c'est la vie. I'm sure there will be a second one of this.
