The game looks great and I like how it looks. I obviously can't give full stars though since it is mainly stock assets.
To me though, the main draw of Turn based RPGs is the adventure and not the battles. While your battle mechanics are very fleshed out and a lot of fun to play with I can't really say that the loop in and of it self is that fun.
Also for some reason I cannot clear the blue girls tutorial. When retrying she only starts with 1 hp and when continuing to the main battle the rest of the party is absent. Maybe also make the text crawl in the beginning skipable.
Overall it's a good entry.
