hi claire! i'm a hobby musician with a couple years of experience. i can do something with the mood/samples you've described, if you haven't found a composer yet! here's my soundcloud, and here are some links to songs that vaguely fit your theme. i have a LOT of samples in a number of different genres, and judging by the examples you've given, i think i can definitely do something for you. i don't charge for game projects since i like participating in them!

i also have pure 8bit samples and others samples on my commission page.
