All you have to do is complete the game. Don't worry about lives as they aren't necessary to complete the game. For example, if you lose all your lives at 13-4 then the game ends. Once it has ended, all you have to do is start a new game and you can begin from 13-4 with 3 lives.
Here are the following levels with the number of rounds:
Level 1: 8 rounds

Level 3: 10 rounds
Level 4: 12 rounds
Level 5: 12 rounds
Level 6: 12 rounds
Level 7: 12 rounds
Level 8: 14 rounds
Level 9: 14 rounds
Level 10: 16 rounds
Total rounds = 120
Tips:
(1) Use LT and RT: These are useful as it lets you dash from left to right quickly. You should be making moves quickly and then use LT or RT to catch important power-ups.
(2) Don't Always Get Jungle Rumble Power-Up: Honestly, this power-up is nearly useless in most situations and can be detrimental in some. Quickly assess your situation and see if it's worth getting this. This particular power-up causes an earthquake of sorts and fills in all the gaps.
(3) Speed: The faster you play the more power-ups you unleash. Power-ups, in later levels, will largely determine whether you pass a level. Make sure you're precise at the same time so you're not just wasting moves.
