The graphics were nice, but obviously inspired by Limbo. As for the game play, some of the jumps (namely the S-shaped tunnels) were very difficult to use, since the character isn't exactly fast, and the ghosts can move through walls. If you stopped or were caught for a second, the ghost would just move through the walls above and below you, and kill you almost instantly.
Also, there was no intro, no tutorial, the only real directions for the game (light the lanterns) were in the description. I really could have used some kind of plot, something telling you why the ghosts were after you, why you were alone in the dark, even what the window that lit up with the lanterns was.
3.5 out of 5, I think it could use some polishing.
