I'm going to start by saying that I'm not really that into traditional rpgs, so I know this game wasn't really aimed at me, but I decided to give it a go anyway!
There's quite a few typos, and just one of my pet peeves that text doesn't fill the textbox correctly. It's slightly strange that only Komui's dialogue has his name. If you want to have a proper namebox window, you can take a look at Yanfly's Message Core, though consistency is really ideal. Your narration can be inconsistent sometimes too, going in and out of third person and past or present tense.
If you're not a fan of mapping (who is? XD) using premade maps isn't taboo, but you really should put the extra effort in to change a few of the tiles around. The target audience for rpgs made with RPG Maker is mostly other rpg maker devs, and we've seen these all before. Using the same inn map for Minich'i and Daricha was really confusing too.
Because of that, I didn't really feel interested in exploring your world, which was a shame since it did look like you'd put the effort in with the backstory and npcs. I love your random generated characters though haha.
I decided to become a mage, but felt that battle balance wasn't quite right. Some enemies like the slimes couldn't lay any damage on me at all, and there was some I felt like I couldn't lay into. You've got a huge range of troops so it does keep encounters interesting, but your encounter rate was pretty high, especially on the world map, so it felt grindy to me. (Again, bias since I just don't like turn based battles, but...)
Apart from the typos, I noticed you'd used the wrong sprite for the face here;
Not sure if this was a bug, but I ended up in the desert and was told that I should go to the mountain pass first, but I didn't get warped out of the map so I could have continued that way. I didn't get far enough into the story to find out if that would have caused issues.
Trying to enter places I can't usually brought up a message saying I wasn't allowed although I was respected, apart from in Minich'i where I was still apparently a kid. It could be a style choice, but it was slightly weird that none of the buildings had doors. You can quickly make doors by right clicking and using quick event creation if you weren't already aware.
So I made it to the mountain pass (after initially exploring and then forgetting where I was going,) and then was promptly killed by a mimic. I know you warned about those, but they were pretty tough. This was about 30 mins in, but I decided that it wasn't worth it for me to continue, since it's just not my kind of game.
My advice to you would probably be to streamline your story a little and focus on your characters a bit more than just making a vast world that a lot of people will probably skip out anyway. Even if maps and graphics aren't your thing, I think you do need to put in a little more there to help you attract more of the rpg veterans who've seen all the rpg maker mv resources before. There's so many things out there like these npc emosets. If you spend some time checking out this forum, you'll find an unbelievable amount of resources. Hope this helps a bit, and happy making! :D
