Why is that so many past games end up getting repeated for the current iOS gaming space? Well, for one, it is because it just is so easy to control games using a swiping interface. And really, that is what the iPhone is made for. So, with that said, this is why Bubble Rival - A Puzzle Racing Shooter for Mania Guppies is still worthy of a download. For one, it mimics the Bubble Bobble formula quite well enough, even right down to its cutesy characters and colorful graphics. Of course, you also have the option of “upgrading” to different weapons as long as you progress further and further down the game.
