Nontan to Issho: Kuru-kuru Puzzle (1994)

Nontan to Issho: Kuru Kuru Puzzle is a game based on a children’s anime and book series telling the story of a young kitten and his animal friends. It is a block puzzle game the likes of Tetris and Baku Baku Animal, where the goal is to stack blocks in a way that matching ones are connected and therefore disappear. Unlike in Tetris games though, the blocks cannot be rotated – they can instead be flipped around to reveal different blocks on the reverse side. There’s also the usual bonus blocks that remove entire rows, as is common in this genre. A two-player mode is also featured, even though unlike what usually happens in two-player gameplay of puzzle games, the actions of one player will not affect the other directly (like having more blocks falling on your opponent’s screen after you scored pretty high).
