Another interesting aspect to the game is the score you get for each level you complete. How do you max your score ? Well, you earn points from doing things quickly and comprehensively. Also, don’t get killed. It tends to slow you down.
You get points for each treasure you collect. You get points for every enemy you slain. And you get points for how fast you complete the level.
Being thorough is also rewarding as you get bonuses if you manage to collect all treasures in the level and if you can take down all the enemies.
Of course, this takes time, which lowers the amount of points you get from finishing the level quickly, so you need to balance them out to get the most of each level.
