Is this project dead?

I remember seeing this years ago and thinking it looked promising. However it still seems unfinished. Are there any plans to complete it? Is it possible for people to contribute?

Hi, this project is not being worked on for the past few years. I am not sure if any active forks exist.

As of now, I have no plans to finish it, though it is mostly finished already. Up to level 8 everything should be implemented IIRC, while later levels are also there and are playable, but boss logics are not implemented.
