Woah. I was not expecting something like this to be done in one sitting. I'm very impressed it sounds like you worked on it for weeks.
I really dig the perfect harmonies mixed directly in with some dissonant, ugly ones, I think it sounds a lot more real than just the same 3 damn chords over and over again. Plus, it adds that human element of error that is, I believe, necessary for it to be "good" music. Also, that lead synth that starts around 1:21 is so cool, how it morphs from that subtle undertone to the ghostly wail afterward. Reminds me of an 8-bit haunted house. I also downloaded this one. 5/5, man you're awesome. I am now officially your fan lol
Please contact me if you would like to use this in a project. We can discuss the details.
