Sounds more like a community mod than a project
Perhaps, I'm not sure what defines a mod or project. The source provides enough to get started and there is plenty of room to add. Depending on how th community wants to pursue development, it could end up being a totally different game in the end. As you've already written most of it beginners are unlikely to learn much. Why not finish it yourself?
I've only provide some basics. Basic collision, particles, enemies and player code. Adding music management, network multiplayer, AI, etc could be a great learning experience.Ultimately, it would be interesting to see what kind of games evolve out this code and game play concept. Its here for the taking.
