It looks like the source repository link is dead?
Could you please post an updated link?
Thank you for your attention ! Indeed I had to change my gitlab username for my exams; I changed the link in LudumDare entry.
For a short access, please follow this link : https://gitlab.com/esilvert/LDJAM_36
Hope you'll like it :)
Edit: As it was made with an older Godot Engine version, you might have to use it so it execute sucessfully.
