You already discovered the crux of the game, heh heh. Elven Paladin was designed to need at least 4 playthroughs to get every spanking. I thought that was the fun of the game but when I got calls for a walkthrough, I figured maybe not. I want to tell an epic story this time and it would be insanely unfair to expect people to play something this long again just to get something they missed. Most of the choices and options are cosmetic. Whether Bulwark is a perfect angel or cursing out orphans, most of the story will go the same way and you won't miss anything. You will get different reactions, but all roads lead to Rome as they say.
Same with the spanking scenes. You can dress Camilla up however you want, or even if you decide to make Bulwark some armor instead, Camilla is still a manipulative brat that needs to be humbled with a butt whooping at the end of the demo. I personally love it when a woman is getting spanked on her panties with her pants pulled down, but I think I'm the only one on the planet that does. So I wanted to make it whether you like pants, skirts, leotard, panties, bare ass, wedgies, hairpulling, you can have it your way.
Thanks for playing, and your kind words! I hope to live up to your expectations!
