Incredibly polished game! I really loved the use of bloom, the 3D audio, the chanting sound effect (all the sound effects actually), all these really gave the game a spiritual and spooky mood!
I think my only nitpick is that the night lasts a bit too long. There's a bit of downtime before the game gets to the spooky part, and it feels a bit too punishing (i.e. one touch of death) given the amount of time it takes to get there.
But overall, fantastic work! I really enjoyed it!
