Hi anon, I would be happy to offer you some music for free. At least at the start. My policy is, if you are not gonna make any money, I will make it for kicks. As soon as you publish it and money starts rolling in, we can talk about my fees according to what you can realistically pay me for. I am a huge Sonic fan, and a friend of mine is gonna publish a game that I composed for soon. Just send me an invite to whatever Discord server you are making this in and I will show you some references. That is, if you are still looking.

My Discord is brainstormfenix, you can reach out to me that way
