The music and graphics are good, but the gameplay seriously needs some rework. Rather than using the [right] key to shoot, try designating a specific key to use with the opposite hand so a player can shoot *and* move at the same time, and have the chargeup continue while the key is pressed, rather than auto-shoot and charge when the key is not pressed.
Since gameplay is the key behind any game, no matter how beautiful it is presented, this one only gets 1.5 from me.
