already doing the trial and error, which is the basis of my post lolz. You could do it similar to the map items you already have that note names of locations, but instead do them as hunting maps to denote what level things are in said areas. You would still have to find, buy, or make them mind you. But it would be an option, especially for someone who puts the game down and comes back but doesn't remember where to go but might remember a map showing where they *might* be going according to their level.
As for the quest log, it does give a very basic direction but like... it doesn't give the details of something like when you pick up the quest and the character says they should try x. Like I could not figure out the wild herb location till I *very* randomly find the side path to a forest where they were a replenishable pick up item. As for some of the other quests... let's go with the first side quest you get when starting the game. It's to open the skill tree. I'm playing on my android, so I'm unsure if the other versions have a different menu... but I kept thinking it would be in the skill menu. Not under the options menu below the sound and graphics settings etc. So I had saved up about 18 or so skill points but couldn't figure out where to use them because, well, I expected that menu to either be under the Skill option in the basic menu or a sub menu to the Skill menu. It's those basic quests that actually explain how to get started, or where to go, etc that give a proper sense of direction. But currently it's just "do this" or "go here" with no info on where or what. It's minor details like these that build a solid foundation lol. Again, I am still really early on, but from what I have played thus far it's easy to equate it to a fancy restaurant or mansion but the foundation is sinking into the sand on a beach because it wasn't properly built to stay up.
I will continue playing from time to time, especially since I'm trying to make my own thing in RPG Maker MZ. I don't really know how to do a lot of stuff, so cracking something open to try and figure out how it works and how to improve on an idea or concept is fun lol. Keep up the awesome work, and good luck with any future improvements :D
