Hello @Vitaliy Kaurov
I enjoyed playing your Bug Hunter web app. The code and the thought process behind this application is brilliant. I did not know the Legacy Animations Documentation pages existed. Its a very nice and intuitive way of presenting it to users.
I got a similar idea at Wolfram Summer School 2016 and built a simpler prototype. Link: [WSS16] Infinite Coding Problems Generator in Wolfram Programming Language . Its called Infinite Coding Problems Generator in Wolfram Programming Language. I used templates and loaded a CSV file that contains questions from EIWL book.
Your web app is so much fun and its giving me new ideas for improving my prototype.
These educational applications has tremendous potential and spikes the learning curve in students. I like to see your app growing big like http://challenges.wolfram.com.
Thank you
