Thank you. I used Godot, you can read a little summary of my jam experience here: https://tackertacker.itch.io/fuzzballmcfuzzface/devlog/143310/added-the-source-c...
I also added the source code for the project if you want to check out that mess ;P
If you want to learn GDScript I'd recommend you start by reading the step by step guide in the official documentation https://docs.godotengine.org/en/stable/getting_started/step_by_step/index.html then play around for a bit and watch everything on the Godot tutorials channel starting with this series
