Roadmap? It's currently on hiatus until my new site launches. So til about Monday, which is also my birthday.
After that, I have one important date planned for the game:
Also known as SMW Central's C3 date. A time where Mario modders and fan game and indie makers show off their work. I plan to release the first demo at that point. I was hoping for all of part 1 to be complete, but... one guy has put his level on hiatus til exams are over and I think my programmers are on a day off or something.
Can you provide a list of features (such as gameplay innovations like wall-jump, custom bosses, imported SPC music tracks or MSU-1 support, etc...) to expect or something?
Feature list for part 1 (demo):
All custom graphics for every level (where necessary)
All custom soundtrack, most sampled
Custom sprites/enemies in most levels
Custom bosses for every castle or world boss level. Some (maybe a decent amount) of simple custom mini bosses in between.
Custom status bar
Custom Mario/player graphics
Maybe some sort of health system
About 50 decent levels, most of a reasonable length and difficulty level (with a few hard secret levels)
Be patient. It's about two weeks til you'll get a demo.
