If you're looking for a simple puzzle game with some narrative on the side, Doctor Cat is something to consider giving a go. I have to admit, there are a few flaws and it does sometimes miss the mark in what it sets out to do, but I like the approach that's been taken with this game, making it something more than just a game with a few puzzles. Although there are things I would personally have done differently, the game does at least provide an interesting challenge, and at the end, you get to replay the puzzles in a more difficult mode.
