I'm new to Puyo Puyo, and I've barely touched Tetris before. I downloaded the demo last night, even though I'm perfectly content to keep playing Zelda and Bomberman. I booted up the demo...
...and three or four hours later, I put it down. WOW. This is FUN.
I'm terrible at the moment, mind you. I struggle to beat the CPUs, and of the countless matches I played, I only won once or twice. But I don't mind because it's all so much fun, whether you're playing pure Puyo, pure Tetris, or Swap Mode.
I find myself growing faster and faster, trying to be a bit more strategic, actually keeping an eye on the "what's next" panel, and trying to think ahead, i.e. leaving a vertical gap in Tetris so you can clear multiple rows at the same time when the "I" block arrives. It's still more instinct and intuition than thoughtful strategy at this point, but it's still fun.
Eager to try this one with friends. I think I'll pick this up.
