Bonuses
You will have a choice of bonuses between levels. Consider choosing extra hearts when possible if you have lost at least one already. This will help you progress farther. If hearts are not needed or are unavailable, choose a bonus that is always active that will always be beneficial, for example the extra bonus you obtained by collecting crystals, or the trophy awards bonus points the small monsters are killed.
Continues
Watch the advertising videos in order to continue a good run. Because they are limited, only view them when they will have the most effect.
Hazards
Avoid hazards such as the large monsters or spiky boards in order to progress as far as possible. This will allow your score to grow as you collect as many crystals as possible.
Movement
Do not remain idle, Always try to move, especially upwards and downwards if possible. If you move left and right, you will have a difficult time. Take the paths of the monsters into consideration by noting the dots that they always follow. Try to quickly squeeze between them and get past. After passing the locations where the monsters are active, you will be safe.
