I once again forgot about this, as I meant to get a refund at the New Year. I just contacted TheGoatStore and got my refund within 10 minutues. Good on them for honoring it.
I'm done with this "project." This project falls just behind Elysian Shadows, as stuck in dev hell and never seeing the light of day. These are the kind of projects that will kill any faith in the Dreamcast homebrew scene. Taking money, producing nothing for anyone, and eventual radio silence.
