The best way I could recommend Kersploosh! would be to have a friend or two with a 3DS agree to buy the game as well. Turn on StreetPass, so every time you see each other after playing, you’re updating your scores and challenging each other indirectly. It’s something you’ll want to do, as well, even if it's a little bit of an unrealistic thing to ask in order to make this game fun. Kersploosh! is a fun, if brief, game.
