Love the feel! This is going to be great background music in the next D&D session I have that takes place in a dungeon. Thank you for making this! :D
I don't know what you could've improved on as I truly feels this encapsulates the feeling of being in a dungeon, lost with no bearings, unaware of what terrors may lurk behind every corner.
I get that feel of Deepness and the darkness hidden inside but it feels a bit more like deep sleep than dungeon.
Please contact me if you would like to use this in a project. We can discuss the details.
