Hey, superb job. Was toying with putting together a walkthrough (or flowchart) myself, but having seen that, I think that's pretty damn definitive :D
Yep, I skimmed over both, and noticed the Steam one lets you hide things with spoiler blocks too, so things like the identity of the 'green route' remain hidden unless you specifically mouseover - neatly done!
Basically, a VN this good deserved an equally good walkthrough, and you delivered in style - if you were to equate it to a hand of cards, it's probably like being dealt all kings ;)
