Every level has three different point objectives, with the top score being the highest score out of this list. A really easy level to do this on is the first level, the Temple of Light. Here is how the point system works:
*Gems: 1,200 Points each. These are very important to collect while going for score challenges. Not only do they give you more points, but they help also help build your Power Meter. They are mostly found around in the environment, but can also be dropped by enemies. Be thorough, and explore every nook and cranny you can find.
*Enemies: You get a base score per kill, and the score depends on the type of enemies you kill. When your Power Meter is halfway, you will gain twice as many points per kill. When your Power Meter is completely filled, you will get triple the amount of points per kill. If you get hit by anything, your Power Meter will begin to empty itself.
*Survival: For each death, you lose around 5,000 points. Dying once or twice can hinder you from gaining the top score, so be very careful!
It's important to visit the glowing tombs while going for points, as some have gems or enemies in them. If they don't have anything, just move on.
