If you're having trouble with the Elves, or the Angel/Demon War, then just get more Pearls. With enough, you can do damage, no matter where you click an Elf Girl. I currently have over 100K, and I easily crush them. If you need to earn Pearls quickly, go to the Countryside. You can earn a TON of Pearls there really quickly, if your Click Power is level 250+. If it's not, use the W+P+N cheat to earn 5Q per use. Using it once is enough to cover the cost for Click Level 250 .
The pink Skip Button is very costly: if you can, try to avoid using it. The more levels you try to skip at once, the more extra WP you're charged for it, up to 2.5x the combined cost of the levels you're trying to skip.
As for Click Power, it gets up to 10 QT by level 400, while Spiral Power remains at 10M. I'm getting the impression that once your Click Level is high enough, Spirals become unnecessary. If you know all these tips, you can easily progress the story.
