Have you ever tried completing your own game? And drawing shields? I don't think you tested your won game because you cannot draw shields...Everything except red missiles[Which only appears in 1 level!] goes straight through everything you draw!
Coudl have been awesome with a sotry line/goal and perhaps upgrades or unlockable's and maybe achievements...Like combos in a row, get 6 doubles, survive for 20 seconds stuff like that...
