Help with movement for parallax maps

[Shadowblade]

Currently planning on making a game, and for the first time I'll be tackling parallax maps. From what I've researched these are an entirely different beast then anything I've dealt with so far, I believe I have what it takes to make them, however the biggest issue lies in the movement. I'm wanting to have a tall sprite being able to freely move diagonally in the parallax map rather then being restricted to the grid. Something like this video here: https://www.youtube.com/watch?v=gzQz_rH8ZB4 (He follows the grid a lot but he does move diagonally a bit FYI)

In the comments the guy who made the video said he was using a lot of Quxios mods, I imagine he was using Qmovement and his colliders. I've taken a look at them and they seem wicked complicated, plus the fact that it seems like I'll have to take into account how different movements for NPCs and transfers to different maps will be. PLUS Qmovement doesn't work well with followers, which I plan on having in my game.

My main issue/question is this: Is there a simple mod that lets me achieve that freedom of movement, without requiring me to throw everything I currently know about RPG maker out the window?

I have no doubt I will need to learn new things in order to make this work and I am willing to do that, but Qmovement seems to be for people who know what their doing and then some, I like to think I know what I'm doing, but not to the extent I need to be to use this plug.

Additionally, if you believe I should just entirely forego the freedom of movement and stick with the grid based movement, what would be your reason as to why I should do that?

I use Galv_DiagonalMovement.js: https://galvs-scripts.com/2015/12/12/mv-diagonal-movement/

(And if your actors are also wider and not just taller, you can have them follow you at a bit more distance with this one: https://forums.rpgmakerweb.com/index.php?threads/follower-distance.120928/
This puts more space in between the actors. And works fine with the galv plugins.)
