Godot is the free and open source game engine that I'm using to make TrackMaster, and I've made a flashtalk about the TrackMaster development to be presented at the Online GodotCon 2021.
UPDATE: link to the YouTube video.
The event will be free for everyone, and the streaming will happen at the official Godot YouTube channel, on July 3rd.
The TrackMaster talk will happen inside a section starting at 15h40 (UTC time).
After the event I will share here the direct link to the TrackMaster presentation.
