Google Game Builder what I really like to use to teach because it’s using JS. Not that I used it many times but it’s really engaging and at least you interact with a “real” language.

It was killed by Google (ofc) but still available and works perfectly https://github.com/googlearchive/gamebuilder

The last full build (binary release) is here https://github.com/googlearchive/gamebuilder/tree/master/bui...

Here is the original trailer https://youtu.be/l9Mf_XEZq-A

And some of the tutorial videos are also available https://youtube.com/playlist?list=PLuYHfxlxFzb25nWnevSN5wQVO...
