I also got very, very tired of trying to hammer elements into Ren'Py that the engine was very much not designed for (like an RPG-style overworld).

It took me about an hour to make a map in Ren'Py, and about ten minutes to make the same map in Unity. This won't be too much of a setback time-wise, since so many things will be easier for me to handle now. Plus, I have actual progress to show! Look!
