I've decided to give away the assets I made for this project for anyone to use. There's a lot of music clips, a couple of meshes and their textures. They're CC0 so feel free to use them for whatever you want, no need to credit me, just don't sell the assets by themselves (putting them in a game and selling that is perfectly fine).
