Honestly I could not figure out how to get past the first level and its two.. zombie ducks? (They're too tiny I couldn't make out what they're supposed to be.) They can shoot in every direction while I can only shoot horizontally it just feels unfair.
There's a toolrack (?) to the top right and I have no clue what it does except block my shots. Maybe it's just decor? But then that would be the single and only piece of decor in the whole room. It just feels out of place.
I've tried clicking on it, but it doesn't do anything. Actually clicking does not do anything, anywhere. And yet you're giving me an audio feedback clue? So I'm guessing I will unlock something to do with clicking at some point (or would if I had kept playing)
