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.
