Before this thing dies out, I wanna say that this game has always fascinated me about game design. I was interested in computers and Sanic Ball was one of the few games where I wondered to myself; "How does this work?", as a young teenager.
Now seeing it be open source, after the developer left it due to disinterest, I have a desire to continue it myself. There have been a few revival projects, like "Sanic Ball Custom" and "Re-rolled", but I want to make a version where it would be up to the community to help it grow, and I feel like that's what made the original game fun.
I was there back when it was popular, and to be in full lobbies, chatting with people and with them wanting more from the game; levels, characters, and features, I would definitely like to make a larger and more accessible base in which the community can add to it and have that be part of their own servers rather than just downloading the entire source code and praying what they added doesn't brake the game.
