I've been toying with if to use music of just ambiance in my game. I've fallen in love with the work of DOS-88 who makes amazing music you can use in return for credit! Check out one of his itch postings HERE. Sadly I feel music doesn't fit the atmosphere I'm going for so I won't be able to use his work but I thought I'd include this here in case someone else was looking for some good synth music :D
