The writing was very good, but i really disliked how it was so much. Don't get me wrong, I love me a good lengthy story, but it seemed to drag on way too much, even at the very start of the game. Being stationary all the time just reading instead of exploring or fighting was boring to me personally, and I would love for the same writing to be used more scarcely or being able to talk unprompted and a bit more optional.
Having some experience with RPG maker as well (I loved using it to make short games for myself), the background is very confusing in my opinion. Misplaced cracks that should only be in walls ( I found cracks on poison water, a lake and on trees).
The combat is interesting, but the tutorial being exclusively text and throwing you straight into battle was boring. Experimenting with this battle system is fun, but without a good first experience with it , i couldn't really pay much attention to what everything did.
It is a very solid prototype, and i would love to see it becoming a full fledged RPG! Congrats on your game, and i hope you will keep updating it!
Edit : On the beginning scene, I would advise to make a blank map an insert the trigger for the scrolling text there instead of using a premade map. That way there won't be any weird transition.
