Excerpt: There are two major subgenres in puzzle games: things falling down ( Puyo Puyo! or the seminal Tetris ) and things switching places. While such simplicity should be boring (and in most other videogame genres, probably would be), in a puzzle game it's almost beautiful in a Shakespearean sonnet sort of way. With only a few basic rules, a good puzzler is both comfortable and pushy. We know how it works, yet in its familiarity it asks us to do better.
Conclusion: Zooo isnâ€™t the deepest or flashiest puzzle game, but it gets the job done with a pleasing aesthetic style and solid, pick-up-and-play dynamics. Kids and adults will like this one for its simplistic appearance and deceptively challenging gameplay.
