Competitive Casual Puzzle(?) Game, Easy For Anyone To Play, Not That Difficult A Puzzle, Enjoyable To Exchange Lots Of Attacks Two-player Battle (Player versus Player) Is Possible On A Single Smartphone [The Rules And Controls Are Simple] Touch around between 2 hexagons to exchange contents of the hexagons. Connect as many of the same colors as possible. Change to "Energy Release Mode" and Touch the large connected area of the same color, a big attack occurs.  If you occupy the opponent's all hexagons, you win. [Easy To Exchange Lots Of Attacks] Many competitive puzzle games are difficult to exchange attacks freely. But in this game, you can easily enjoy exchanging lots of attacks each other. [Two-player Battle (Player versus Player) Is Possible On A Single Smartphone] It can be played with two people facing each other on a single smartphone. [You Can Play Against The Computer] You can play against the computer. You can play against opponents with various thinking patterns. (Currently, there are 13 types.) There is also a kind story that is a little fun and can be useful in life. You can always choose who you want to play against. (You don't always have to play in order.) You can specify the computer's operating speed. Therefore, you can make your opponent weaker or stronger depending on your level. [You Can Challenge Alone] You can challenge alone how fast you can reach a certain score. You can specify "Number Of Hexagons", "Number Of Colors", "Goal Point" to challenge. You can also view your past records. [You Can Specify Battle Conditions] When you play against other human or a computer, you can specify battle conditions. You can specify number of hexagons and number of colors and attack multiplier and others about you and the opponent. If you change battle conditions, game's characteristics will change and you will play in various ways. Some people are good at this kind of game, while others are not. If you could specify battle conditions well, even if there is a difference in ability, you could have fun together. Also, when you play against a computer, you can specify so the computer is not too strong or not too weak. [Quick Startup And Fast Screen Transitions, Ad-free] This system is designed for quick startup and fast screen transitions so that you can always play right away. The logo doesn't appear for a while after starting up. There is no animation when transitioning between screens, so it doesn't take long. There are no long loading times before the game starts. This game does not display advertisements. [Battery-friendly] This app is designed for battery-friendly. This game doesn't do high-speed continuous drawing on screens where it isn't necessary. Even in the game screen, this game does not continuously draw faster (by GPU) than necessary. [Enjoyable Even For Spectators] Because the rules and controls are simple and easy to understand what shape is strong, it's enjoyable even for spectators. [Easy To Operate With A Smartphone] This game (screen design, operation method or others) is designed to be easy to control on smartphones. We've designed it for easy one-handed play with a vertical screen. [This App Does Not Access Your Personal Information] This app does not access or collect any of your personal information or data from your device. [It Might Be Good For Brain Training] You can use your brain in a fun and easy way. This game might be good for brain training. [Truly Enjoyable For Everyone] We developed this to create something that everyone(including people who don't usually play games that much) can truly enjoy. We didn't create a run-of-the-mill game. We didn't let ourselves be bound by conventional wisdom. [To Make A Kind World] And, we developed this app so that this world will go well circulatively, we developed this app to make this world a kind world.
