Its coming along
It's turning out really well but you still need to do some work on the scripting. You need to aim for making it play exactly like the real metal slug games in order to get the best effect. Here are some little things that need to be fixed:
1. A jump button (obviously)
2. Make the player able to shoot in all directions
3. When the player shoots make him unable to move until the shooting animation is through so your bullets don't dissappear in mid-air when you try to move after shooting
4. Make the player able to shoot while running.
5. Add grenades and a knife you stab them with up close (like in the real game)
6. Ok I know the sweat is supposed to be there, but see if you can make it red instead. That would kick ass.
