A. Scratch software.

Advanced students craving more of a challenge can be taught more of the “algebraic” concepts.

Hello lingo1357!

I'd say that the most easy way is to use pygame. You can have a basic game with aout 500 lines of code - including a title screen and highscores. Here's one example I did: https://github.com/dkrajzew/tempo120​

It's of course nothing that you could sell - well, maybe on itch.io if you package it. But for learning basics, it's great!

Sincerely,

Daniel
