The shields are temporary as they disappear quickly so you need to draw them at right time on the right place. The more monsters you kill the more points you score. With the increase in level, the number of monsters throwing the boulders also increases. You can submit your scores to set your rank in the leader boards at the end of each level. This part of the game makes it competitive for the kids as they will score to rule the score boards. Kids will love this game and it’s a good time pass.
