The anatomy in some of the scenes is a bit janky. Personally I don't think the intro serves any real purpose, all it does is set up the premise, everything else is quite drawn out and isn't really relevant in an important way. I.e. the interaction w/ the grandma doesn't tell us anything interesting apart from 'protag is a generic nice guy who gets along with old ladies', the train station scene doesn't tell us anything apart from 'protag has generic emotions about new situation', etc. Might be a good idea to either cut it down and make it brief (the story shouldn't need to rely on exposition to characterise the protag) or make it relevant/interesting in some way (foreshadowing). That's kind of a nitpick tho. Also adding interactive mini games makes these kinds of games more immersive and actually fun to play.
