Some suggestions...
...from a guy who has yet to develop a game. Stinkoman would need some tips:
-Set it so that when you drop, it's quicker and less floaty. And only have him flip when you press the button.
-Restart: Set a point at the bottom of the screen that, when passed, will set Stinkoman back to starting point.
-Attacks! Really awesome stuff!
All in all, glad to see a fan of Twenty-Exty-Six.
