Thanks for your review!
I've been looking for music long time because I can't make good music myself. I finally found this one, I liked it. I thought it could add some energy to the dark atmosphere of the game.
But it's normal that not everyone likes it.
As I noted in the last comment, the game is a bit too difficult. But as I said, I only made the game for the jam and actually didn't plan to develop it further.
Thanks anyway, suggestions for improvement and criticism help me not to make the same mistake next time.
