Sooo let me see if I got this straight...
I press and hold the down arrow, then I press either left or right arrows while also holding the ctl key... sound like a game of finger twister.
Do you press down and let go to activate super state, or hold?
Is this a platformer, side scroller, or other style. Which?
How far forward are we "spranging"? Is this a jump action or a lunge type move?
Does Super State have a timer or burn out period if never used?
Answers these and I can probably throw something together as an example.
