I don't know, I kinda like it to be honest, most RPG Maker games problem lies to grinding and poor combat systems which well this game doesn't have.
Well, this one has pointlessly long traveling through identical-looking empty rooms, a bazillion unlabeled doors, and poorly implemented door transitions that cause you to go back through the door when you start walking, all owed to poor usage of the RPGM engine. Tip: make all door events like the ones on north walls. The others are just awful.
Then, in a RPGM game, NPCs should exist at all times and have a bit of dialogue when you talk to them. Here they just vanish until they are needed for a scripted event. If you're making a walkable world, it should be consistent.
Not an RPGM issue, but I'd also consider smoothing out the dialogue. There are too many passages where the characters seemingly forget how to form proper and separate sentences. It's okay to get help if english isn't your first language.
