I Made My Own Programming Language — Can Someone Test It?

Hey developers 👋️

I'm samwise1776. I've spent six months creating free software.
I recently built Velice, my own programming language!
It supports functions, classes, pattern matching, and desktop GUI development.
I'm looking for my first 10 testers.
GitHub: https://github.com/samwise1776/velice
You can try it on a computer with Git and Python 3.10+:

git clone https://github.com/samwise1776/velice.git
cd velice
python3 -m velice run examples/hello_world.velice

Please tell me whether it works on your computer!
All feedback is appreciated.
