Some more feedback on hitting/killing enemies would be good. I'm not sure if there is no end-state or if I just failed to understand what to do (I killed all the enemies and that was it). If so, I'll just assume that's for lack of time. A personal pet-peeve of mine: don't make me mash the shoot button if there's no reason to. There is no ammo-management or anything. I don't have a reason not to spamm-shoot, so just let me hold down the button :)
