since the only part of this that matter are the graphics, I'll only comment on those. the map is nice enough, seems to follow the "three tile rule" or at least it doesn't seem overly repetitive. UI will obviously change late in development as per usual dev cycles so it's okay for now. but i believe there is an option to disable parts of the UI you're not going to use in RPG Maker, though it's been years since i've looked at the program. if you're not gonna have stuff like magic/skills then you should turn that menu off for instance, something to think about.
biggest bit of feedback is that the player sprite does not look like it belongs in the world. besides having crushed pixels itself, its own pixels are waaaaay smaller than the ones in the world. make it consistent one way or another (either resizing the world or resizing the player) and you'll have a much better looking game.
i'll keep an eye on this
