Wow, I really like that maps. As I told you on MSN I love the tiles. And in gameplay they look awesome!
Continue with this great job and if you need help (though I don't know nothing about Game Development)...
Anyway, good luck~
The tiles look pretty nice, like them. and the story flow seems to fit, but i see one minor error if you didnt fix it yet. between winterflow city and route 1 in the last screens it goes so quickly from a cold climate with snow to a warm climate. I would say make it blend it more. Just a suggestion.
