Glad you're gonna find time to update it! Looking forward to that. I'm very much interested in making a project with the same aesthetic of this (been watching loads of videos about classic JRPGs lately), so I was thrilled to see someone nailing it. Gives me hope I can pull it off in the future. :)
My first controller I tired to use was a Logitech Gamepad F310, which is pretty ancient at this point. It usually works fine, but thankfully I've got the PS4 I can steal from in the other room.
