So, for the PCP project, here are my initial reactions. Since I couldn't find any story triggers, right now I can only give some Words on things that aren't related to your characters or story.
1) Your title screen was nice in that it wasn't the garish stock screen. I personally wouldn't use Japanese characters, but A) someone already mentioned this and B) this is only my opinion after studying the thing for years upon years before realizing I preferred language mechanics and cultural shifts to vocabularies and writing systems.
2) I know it's an alpha demo, but it really kinda threw me into the middle of a city with no prompts at all which, unless you don't have any story triggers, contributed to why I couldn't find any of them.
3) Your maps are kind of prohibitively HUGE. I mean, scrolling maps give a sense of a vast world, but sometimes there's just too much to scroll through.
4) Speaking of maps, you should go into your Autotiles first thing and switch the game's Passing rules on them, because I got stuck 2 West 1 North of the starting screen because I couldn't go back to the screen I came from, and couldn't get off of the Autotile set I was standing on to go to the east.
5) Some of your background images aren't designed to be infinite loops, so they look weird when they run out of space and go back to the beginning. There was supposed to have been an attached image, but long story short, it's the island you warp to 3 West 1 North of the starting screen.
6) I did like how you made those little arrows to show that I could interact with them, either through a transition or by jumping or whatev'. A fun way to show important tiles, or that you can interact with the environment.
7) Not to slight your composer, but the song you have at both your title screen (and as your main city theme, apparently) started to kinda... y'know, after a while. You know, when a track loops over and over and it's like listening to a clock tick when you're trying to go to bed. It can drive a man insane.
I'll explore the world more later, but these are my initial impressions. tl;dr, I got no directions for navigating a map that is way too big and partially unnavigable, the music is kinda crazymaking, and you put nice little touches into it that can lend a fun sense to the game.
