1. If you are going to create a demo of your fangame before releasing the full version, I'd say post it on the JCF. You get less in depth reviews, but more people are likely to comment on it, and some people are going to play it enough to actually find bugs. Plus it's probably against the J2O rules.

2. ...Devan's sprite is ugly.

3. Wait... lemonade stands are illegal?

4. Have you ever seen a game where the evil villain just adopted a sensible plan to destroy the hero? It's always something nice and complicated. And you can't forget that Jazz has extra lives and Continues.
