That's so kind, thank you!! I'm super glad to hear that it brought you back, it means a lot :')
The source code is open if you're interested, I was thinking of putting a copyleft license but I have to read up more on the details. The Godot stuff is on the top-level files while the language stuff is under the "code/assembly" directory. Sorry it's a mess lol.
We don't have any plans currently on expanding it, but we might consider it at some point. If anyone wants to reach out I'd be happy to listen.
Thank you for playing and writing! :')
