As one wise, bookriding cat once said "Where's my fishy fish fish dish? Meow!~".
All achievements can be unlocked under an hour, which is around 3 replays of each location.

Simple and straightforward: find all cats spread around each one of the 9 included scenarios. Once all completed, they can be replayed with a few extra cats included. Optional 1-cat hint available after a set period of time passes.

Artwork is cute, the gameplay is relaxing, and there is a decent variety of music included to boot.

There are some complaints about the 1k cats achievement, but unless one has managed to memorize the location of every single kitten on the maps there is some space for replayability, especially with the extra cats thrown after completion. Myself did not find it grindy.

Likely the best game of this kind in the Steam Store, at a very good price. 10/10

Cats!
