Just finished playing this delightful little game. I loved the little meows so much that I kept finding myself clicking on the cats I'd already found just to make them 'speak'. And the bow-ties on the penguins made me smile.
I did have some slight issues with glitchy graphics and sound but that may be due to running it in Wine on a potato (this is a linux-only household). Wasn't bad enough to get in the way of me enjoying the game, though.
