You sir, fail at life. When the artist says he doesn't like the fact the game looks more advanced than what was originally conceived(Or at least, that's how I interpeted it) I don't think it was meant to be 3d.(This is assuming you are talking about JJ2, not Bagger's project)
Next, I'd like to request you do not add any of the weapon ideas I suggested for Bagger's project. That means say good bye to the Toaster and Blade gun.(I think I did more, but I am not sure).
Finally, I thought we were supposed to upgrade JJ2 not change the whole game(This is why I'm semi against having the source code released). ;[
I think the JJ2's version is named Blue Bullet Bouncers. This isn't JJ1.
