Free, Eerie, Bloody.

-Really cute art style; there are not many places you can go but even these small ones are executed well
-Gameplay is the most simple thing you can think of; left click all the way.
-The story is really interesting, it's a simple gothic idea turned into a revenge story.
-The soundtracks are all free but they are chosen perfectly.

What more else do you want from a free indie game?!
