Oh, nice, I don't know how I missed this project, but I love the idea! I just love creepy stuff (how creepy that sounds like! haha)
Maybe a bit late, but I have a very rough WIP for a track that I think it'd fit this album pretty well. It's a dark/horror/creepy/whatever arrangement of the boss theme from Terranigma, highly inspired by that annoying boss, Bloody Mary. Terranigma's anniversary is in October too and I'd love to make a video with it once it's finnished, so the plan is just ideal.
So far it's 100% MIDI but the structure has plenty of progress. I'm pretty confident with my arranging skills and ideas but everyone in the VGM scene seems to hate my mixing haha, so since this project seems not to be that nitpicky it'd probably be just fine. Still accepting help from performers or even in mixing/mastering if anyone is interested, tho. I can share the latest WIP as reference if that's needed.
