In episode two it's the end. You help her three times to see the full teaser scene, next you can do it to earn shells (and have the teaser repeated). In coming episode four completing the hay quest three times is needed to open the next farmer quest.
When I went back to the farmer, it says something about the next episode, so basically, the only thing I can do in episode 2 is to collect hay? and the scene with the girl and the equipment from Naira will be released in episode 3?
OMG, I cannot wait for it, this is the best game ever, the first of its kind, Adult RPG. You guys are the best.
