Just Finished the demo last night.
It has a lot of Persona vibe (UI/Menu from persona 5 and the characters are making me think to persona 2)
I like the work globally, i'll make constructive critics, maybe it'll help you improve the game :)
Very pleased to see the game is polished on a lot of aspects, but why didn't you change the basic sound effects from rpg maker ? it makes a cheap feeling breaking with all the rest that is great.
Also regarding the UI, some status effect are impossible to read because of a number on top of it.
Maybe the diffulty is too easy ? (Not an objective comment, i play a lot of hard rpg, but if your goal is to do it hard then maybe an increase would be nice, or hard mode)
I wish you the best for the future, keep up the good work :D
