Great as always
Well, it's Frank's adventure! It can't be anything other than good. You improved a lot and made the game work different while staying true to the original's concept and gameplay. This series is turning into a classic. Dare I say... the Flash equivalent of Leisure Suit Larry?(of course, cutting down on the dork factor... or the humor factor)
Yeah, what makes this game funny is how over the top it all is. I love that. It could use witty lines or conversations or funny situations(as in Leisure suit Larry :D) but I know you're not comfortable with the english language and the gameplay doesn't make it easy to animate(or pleasant to see animated, for that matter) anything other than walking. So it's great as it is. While there's almost no plot, it never gets boring since you do it so well.
The graphics are not the best thing you'll find in Flash games but it isn't supposed to be. The logos are impressive. The backgrounds and characters are far from impressive but the average graphics(the menus are great, by the way) make this series all the more unique.
I love the fact that you get to buy songs here and here's a suggestion: Hidden songs. In the next game, you could hide tapes or whatever in the city like behind a tree or something. Listening to the song would be more rewarding then. Oh, by the way, you get a 10 in sound for the Ranma song.
Finally, interactivity... It's a game so I can't give it anything lower than an 8. It would be nice to be able to reply to the characters, though, instead of just being asked for something and walking around trying to find it. But that's just what I'd like to see done, not what must be done. And as it is, it's already damn good.
It's the best game in the series yet(or at least my favourite) and it has definitely the best plot(or my favourite plot...)
