I love the little cutouts and how you animated them, overall it was a pretty fun and unique concept having to go catch the fishies for other cats. Your audio paired nicely with the style you went for, as previously mentioned by someone else it would just be better to keep all your assets looking the same to keep the vibe the same (like the seaweed being a bit more cartooney and the rest are cutouts)
I had a lot of fun playing it tho, good job! :)
