I will be watching your development with great interest...
When I saw your comment, I was like... this prototype needs refinement. So, I worked on it a bit more and uploaded... a more presentable prototype.
I still remember that RPGMaker game jam. It was just a nameless game jam, yet you put your best effort on it. When I analyse the combat mechanics of that game, It seems that you have a decent mastery over RPGMaker, as if that boss rush game wasn't your first rodeo. Can I ask how much experience you have in your belt when you started that project?
Also, I could no longer run my RPGMaker MV after the latest windows update. When I launch RPGMaker, it just crashes. Thus, I could no longer enter another RPGMaker gamejam with or against you. However, I could make an RPGMaker-like game in Godot. So, in the unlikely scenario that you want to use Godot to participate in another game jam, let me know. We could work on something cool.
Finally, I want to express how flattered I am for you to take the time to write a detailed review of that silly RPGMaker game I made.
My only other experiences with RPG Maker VX Ace before that game jam was another game I made called the Alfaoxtrot RPG, based on a youtuber I watched which I never finished (lol): https://gamejolt.com/@HansVinLin/games. Before that was a small game a long time ago I made and also never finished (lol) which taught me the basics.
My best advise I can give to you is to just be consistent. Right now, I'm working on a new project, and I'm aiming on just working on it for a single hour a day, no more and no less; that way, I can both ensure steady progress, as well as guarantee that I won't get burnout.
My only experience with godot, was watching the attached video, but since I'm working on another rpg project now, it's unlikely I'd soon have the required skills to help lol.
