That project is completely abandoned and I regard it as my greatest failure. It suffered from a huge lack of organization and planning, rampant glitches, and there were lots of issues involving memory shortages. The project was over ambitious and had gotten out of hand, so I decided to let it go.
This project, by contrast, is advancing at a much faster rate, and is very carefully planned and documented, so nothing is really exhausted. More than half of the game's layout is finished. The only gameplay element I haven't started developing yet are the boss fights, which I plan on doing last. And I still have a whole bank empty in the rom for future considerations. I think what I learned not to do while working on Cadence of Agony has helped a lot on this project.
