Thanks for checking it out! If the menu music is stuck in your ears then I guess that was money well spent :)
As for my own experiences with Unreal (4 mostly), I like the layout of the engine and workflow. Blueprints is perfectly fine with me because I'd rather connect nodes Blender-style than learn C++ from scratch. But the huge project sizes and considerable hardware prerequisites are what make me wonder if Godot or Unity might be a better option. Like if you make An Awesome Unreal 5 game, yeah that's cool, but how many people are going to have computers that can play that? So that's something else I'm thinking about as well.
