While it is possible to beat Elena the first time you try the game, it's much easier to do that later in the game when you are given the chance to play again.
To beat Elena's score, you need a flawless run with no mistakes.
Each fruit that you collect increases your score. Make sure you pick all apples.
When you play the game the second time later on, there will be an extra life in the box that has Crash Bandicoot's face on it. The extra life gives you a score boost of 500 points.
If you reach the end of the game without getting the desired score, quickly restart the checkpoint to play again.
Destroying boxes increases your score. Do your best to destroy all boxes.
Time is used in the calculation of the score. The faster you finish the game, the higher your score will be.
