This is very nice. Love the sprites. Thanks for the information on Piskel. Some possible "enhancements"

1. Give us an indication on when the weapons are charged. Change in colour perhaps?

2. Might be nice to show what the problem the opponent worked on is and what its result was so that we know.

3. It might also be nice to put the sums solved so far in some kind of list at the bottom so that you can see what happened.

4. The HP bar can change colour as the health goes down. Would add some more excitement to the game. :)

5. Minor typo "chose" your move instead of "choose your move"

I've been working through https://www.amazon.in/JavaScript-Kids-Playful-Introduction-P... with my own son. He's 12. I encouraged him to put the exercises he made onto a site as well as some of the things he wanted to do by himself. We've reached the chapters on the canvas element so more things will be coming. Right now, it's mostly jquery and some custom logic.

His site is up at https://mskv.in/ and if the folks here have feedback, I'd be very happy to receive it and pass it on to him.

On a separate note, it was so liberating to watch him just solve things the way he wanted without worrying about patterns, libraries and stuff. So much of my professional time these days is spent with things like that.
