lolz I did not rip-off FPA's controls. They *Pencilmaster,sausagefanclub etc* made me change the jump button you know. Oh yeah, btw I noticed your character shakes when he is touching the wall. perhaps you can affect the parallax's x axis while your character is touching the wall.
no one person who is smart enough to know how to program is dumb enough to use arrow keys and the s button for a fighting game unless they are ripping off controls from another game. the control scheme for your game is embarrassing. the rest however is pretty awesome.
change your control scheme to something more appropriate an polish up your artwork and you have a good game there.
