Yes, C++ (with SDL for video, audio and input) I know it's definitely not everyone's first choice but it works for me. I have looked at Godot in the past but I have never had time to learn to use it properly.
Godot's easy to learn, but has little annoyances that they haven't finished working out just yet. If C++ works for you though, than stick with it. I'll be interested to see how your project for this game jam turns out!
