I've released 0.1 RC1. Still a lot of work left to be done, but getting there.
I'll give it a time for a while, so I can plan well before working on the 0.2 version, as I plan to completely redesign the editor and filesystem, in a way the game is much more editable.
This should make easier to solve things as bosses IA, once it will be editable by the user (will have a list of possible actions), removing most hardcoded parts. It should take a while, but after that, the gmae should be finished, and I'll try porting Megaman 9.
