Nice game! I really like the music and atmosphere created, that works really well! I was always looking over my shoulder to find when the ghost would be on my tail again, which created a spooky atmosphere, and the noise of the ghost as it approached me, combined with the creepy white eyes, really worked well!
Critical feedback I'd give is to maybe make the souls a little more clear, I couldn't initally tell that they were souls.
Also, if you had more time, some cosmetic differences or decorative props scattered lightly across a few rooms would make it a bit harder to get lost (although now i type this, that is probably the intention)
Solid game and nice work :)
