You best stock up on balloons (the extra lives in the series), because you will definitely need them. I went through hundreds, maybe even over a thousand, lives. Luckily, collecting coins to buy balloons is easy and the coins themselves are plentiful. But man, will you be stocking up on them balloons. I honestly have not played a game that was so unrelenting since I took on the challenge of "Prinny: Can I Really be the Hero?" for PSP, which was another game I really enjoyed, but was fed up with by the end. You see, you've got to be precise with every jump and every button press. You will have cheap deaths and you will scream at your 3DS, only to apologize later when you play an easy-going game like Animal Crossing (review for that coming soon). "I'm sorry, baby. Why do you make me do it?"
