I've just released my first sound asset pack for free on itch.io, consisting of 30 tracks totalling 40+ minutes of spooky ambient sounds. It can be found here:  Unnerving Ambient Sounds - Itch.io

A demo of what's in the asset pack can be found here: Soundcloud Playlist - Unnerving Ambient Sounds

I hope you enjoy it, and any feedback is much appreciated! 

Thanks and Enjoy! :D
