This game is amazing and addictive. It requires some patience and thinking.

You have to complete puzzles. I haven't completed the game but for the moment the difficulty level is balanced and I like it.

Imagine a puzzle full of tetris blocks, you need to move them so you can pass through them with your dog/dogs (another tetris block) and find the exit.

Every level has 3 bones, and a "shortest way" achievement, so you will probably have to repeat the level if you want to complete it.

It's just 6.5mb, which means it's pretty lightweight for the hours of entertaining it will give you.

Highly recommend it.
