The story is definitely the star of the show here and it got me completely invested. The addition of difficulty levels and audio sliders is heavily appreciated, because the audio is pretty loud by default. Like others have pointed out, the sfx get repetitive and grating VERY quickly, but I do love the sound of the shotgun. It's very crunchy. The logo is also very eye-catching and well designed. The gameplay is simple but gets pretty hectic on hard mode and in the later waves, with the enemies' increased speed and tankiness feeling challenging while still remaining fair. I did have an issue where I accidentally clicked out of the tab while aiming and somehow got wedged onto the bottom track of the map, but since I was on the 12th wave it didn't bother me too much because I was almost done. Overall, the biggest praise I have for Shell-Shocked is definitely the interpretation of the theme, which was original and unique!
