Music and art are really good, and the concept is pretty cool. The cat is really well done, with the animation and the sound effects, really satisfying.
In term of gameplay, the cat moves too slow. The trash cans aren't really lined up well for satisfying shots, the bazooka doing AoE and piercing trash is really punishing, and not being able to continue after losing kills the pacing. The enemies are also really tanky, they already don't move or attack after hitting them, so it's basically a more tedious one shot.
Overall it was fun and creative. Well done!
