I've seen lots of games that interpret the theme as controlling two characters at the same time, but none of them is as clever as this one. While the player can control two characters at the same time, each of these two characters' ability is limited, and thus it requires the two characters to help each other to pass the level, which makes this game more fun and creates more possibilities. The levels are all well designed. Well Done! By the way, the artwork in this game is so cute. I love this art style :)
