I have a love-hate relationship with animations, so I'm really happy that you like them (I made them). I did get feedback from my playtesters that a crosshair would have been nice but I didn't add it (mistake). I did try to add a sound when you hit the zombies but it mostly just blended in with the gun firing sound. I agree that since shooting zombies is like the main thing, I should have added more feedback and even made it more satisfying with more effects. Thanks for playing, I spent like 8-10 hrs a day on it for the 3 days.
