Thank god IGN gave Pop a second chance, because after a first-impression they really weren't feeling this short little WiiWare title. Basically, at first glance, it seems like all there is to the game is to aim at bubbles with the Wii Remote as they float from the bottom of the screen to the top of the screen, and then pop them by pushing the A button or B trigger. Hit them for score, miss them and you lose time. Not really all that innovative.
But then, you start seeing the little strategies in the game: pop groups of bubbles with a single button for more points. Grab bubbles by holding the button and pop them somewhere else on the screen by letting go. Inflate grabbed bubbles bigger by shaking the Remote up and down rapidly before releasing them. But it's still just popping bubbles.
