Honestly, If Renpy is restricting you, and you can basically port the entire existing project with little issue to Godot, then why not? I would like the management aspect to be more robust, as that was what I was expecting going into this. I do like that your team has been working hard to polish up the story and the art, not taking that away from you at all, but if Godot is going to give you the tools to realize your vision and make you happier to work on it, then I certainly am all for it. Been following for 2 years and will happily lounge around for a few more.
