Well, was going to suggest with a rivalry this heated, that an ending where they both wind up bound together would be extremely hot... guess you're already on that wavelength.
As for the actual game, extremely solid start. Difficulty is too easy, and bindings, while helpful, aren't enough to sway a fight either way. If fleshed out with more leaders and units, or perhaps shift the generic units to enemy side, and have a cast of unique characters that can be bound up, and you'll already be on a road to something genuinely special.
Either way, excellent little game, though one gripe: the endings have the text boxes blocking out a fair bit of the pictures, and that especially hurts for Valerie's victory. Hopefully that can be fixed in the upcoming update?
Also, from a personal perspective, thank you for including nudity. It's always a personal preference, of course, but nudity always makes the bondage better for me, and this game has a good use of it.
