Really enjoyed playing this. Was instantly hit by the music, which was perfect for the atmosphere you created. Particularly loved the moments where I was running from the enemy because of the tension that was established through their fading into existence as it chased me and the bloodcurdling screams. Also really liked your lighting system.
Something I feel could have been better was the re-spawning/resetting as I would have expected to have to run from the ghost again. This would have created more audience interaction as they have to try and remember when the ghost appears and try and beat it before it can get them.
Overall, cool game and was interesting and fun to play.
