I understand what you are trying to do and it looks like you put in a lot of work but I think that the page is not doing a good job of guiding people through the course. Right now I think the website is very confusing to navigate and it's not guiding people through very well.

I also disagree with the assumption that your own language makes it easier to understand the concepts of syntax.

If it's just JS and people can watch a video about "what does let do in javascript" on YouTube or google "what's a loop in javascript" that makes it easier to understand these basic concepts if you have access to a big variety of explaining the same thing from various angles. I don't think having a "fake" language to learn it is making it any easier. There's a reason people learn JS or Python in school where there's also a lot of editors / resources that can be used even if they are curated in a way to help a total beginner.
