It feels creepy and the palette you used is interesting and away from the expected norm.
I wonder how it would be slowed down or skipping every 2nd or 2nd and 3rd note. The only concern I have is because of the piercing nature of bells (and it depends on how it's mixed into the game) is listener fatigue. You could also try EQing the song and notching out a little 1-3k.
Otherwise great job for settting the mood.
