Hey Monte, great game as usual, one thing do you think you could patch in support for two fire buttons? You can leave the jump as up but also enable button 2 as jump.
Good idea.
But leaving the UP direction active may probably block the use of the UP button (if you accidentally hold direction UP, pressing Button 2 at the same time will not work).
Or you will accidentally jump by doing the diagonal up direction instead of the button, this will be the most annoying.
Choosing either this or this in the menu or with a keyboard shortcut is the most effective solution.
