I feel like the title kinda explains the video, I turned set theory into a conlang and it's very bad (Deliberately).
The music playing for most of the video is by Unicorn Heads and can be obtained from the YouTube audio library.
Music at the end is from monstergarden's collection of Creative Commons music:https://youtu.be/aVFjUe0jfM0?si=fiJhycTXs0T2T79Q
Thanks monstergarden.
