First of all, the theme was pretty intriguing. I haven't played many bath-themed shooters in my time, and the way the player moved around the tub definitely made me feel like I was swimming through it. The music was pretty good and the sounds were appealing. The reticle made it clear where the shots were going, very nice touch.
It feels like it takes way too long to die, I barely get hit by the ducks. I also know that there's meant to be a boss at some point but it seems to take a while to get to it, because I'm pretty sure I haven't seen it yet. It also would be nice to be able to see how many ducks you've shot and also maybe how many until the next wave/the boss.
Good game overall, I just might play it again!
