Your objective is to not only reach the stairs, but to get the highest score you can.
There are many ways you can earn points on a level:
Defeat an enemy to add his max health to your score.
Rescue a captive to earn a reward.
Pass the level within the bonus time to earn the amount of bonus time remaining (each level has a bonus time that decreases turn by turn).
Defeat all enemies and rescue all captives to receive a 20% overall bonus.
But you must be careful, because you can also lose points:
- Kill a captive and you'll receive a penalty.
A total score is kept as you progress through the levels. When you pass a level, that score is added to your total.
