I like it! The music fits the game very well - it isn't scary, per se, but it gives you the feeling of unease.
The only thing I would change here is the tutorial. The first time I played it went on too fast and I missed the last bit about having to activate all the shrines - I thought I needed to look for unlit shrines, so I wondered around in the dark looking for something that wasn't there. When I found out what I was doing wrong, I wanted to skip the tutorial, but the help text kept appearing on the screen.
Oh, it might be a good idea to have some sort of indicator of how many shrines are in that level, plus maybe an information when you've activated them all.
All in all, I think it's a pretty decent entry to the jam. Well done!
