Awww yeah, I love RPGs like this and you captured the feel perfectly. A love letter indeed. The writing's really good as well, I enjoyed talking to all the characters. I also appreciate the prompts, though I really wanted to take the little boy with me into battle.
I wouldn't say it's too difficult. Obviously, I haven't gotten that far yet, but I feel if it's a love letter to classic RPGs it has to pack a certain punch. Maybe not quite Phantasy Star 2 level punches where you spend years level grinding for dungeons, but you know what I mean.
Didn't notice what the camera sway was about, but maybe I already played an updated build.
It's already been said that the music is super good, but I have to say it again. The battle theme was nailed in particular. I hope once you insert non-placeholder music it will still be that great.
All in all, pretty amazing dude.
