Wow, I love this concept! And it probably helps that I'm a cat person :D
I really like how you've interpreted the 'It's spreading' theme with this. I have to say initially I didn't realise you could just freeze the fish anywhere then make bridges towards them for the cat to reach, so I spent a good deal of time trying to wrangle the fish into position on my ready-made bridge to the ship, lmao. But I learned eventually!
The style you've gone for is really nice and the gameplay was great. Nice work!
