Animasu no Shinkei Suijakusuka?
Game: Puzzle, Memory
Another picture-matching game from Sage, which rewards you with girls in skimpy bathing suits that are removed when you complete the puzzle. While the artwork is great, the puzzles are in a fixed order and are very predictable, and the game will allow you to continue from where you left off even if you manage to run out of tries.
