this is brilliant. most of the feedback i'd want to give has already been given though... e.g. the attack charging confused me a bit until i worked it out by inference. the animations are probably the highlight of this for me. they add some character nicely. adding more elements to show the attacks in progress beyond the colour changes would be a nice way to improve this. i would suggest removing 0 from the rng for t…
He needs to think more about "hardness" of a question and what that means. Right now, multiply/divide are considered "more hard" but that's not actually quite correct given the implementation of divide.
Appreciate the feedback! I'm not sure if games are his future, but it's a great stepping stone at the current age as the output is shareable with his friends!
