Hey, just played through the entire game (or what has been made of it so far) and i wanna say that this is exceptionally good. By far, it is exactly what i want for a pokemon game. though a suggestion i have is that id like to see the girls being included in the main storyline a bit more. Cause you see their dialog in the begining of locations but they dont talk or like do anything as you go through. --id like to see like special actions to if your able, like adding special interactions for certain girls in certain location "floors"--
(Before i continue i do apologize if i end up sounding like im down playing the game or criticizing it, im not. I genuinely love this game.)
I think a fun idea that could be implemented later on is like a few different little side pieces of dialog in the story line locations like you can select a girl thats fitting for some locations and you can like talk with them before you continue, Like for example they come out and talk with the MC with like special dialog, like a date at the locations. Not necessarily sexual stuff, but just like romantic interactions between the MC and the girls, but only one can be done per location. Like lugia at one of the water based location, mewto at like a night or under the stars type place, stuff like that. Basically just fun little side stories for the MC and the girls (and im talking about something different from the downtime events section, those are really good though). Another fun part is that with like the group type stuff, like the three girls that look like neko's, the three birds, and even fun little celiby interactions (forgot how to spell their name)
(Note: this is more speculation, even i can see that this would pose lots of difficulty with everything your already doing. I love the game and i hope that it gets even better with future updates. Oh, and thank you for making one of my new favorite games)
