Awesome! It's nice to see how AI can be used for learning purposes. It changes from all the negative things we hear about it :)
As personal feedback, I'd include an animation showing the attacks charging (or at least a notification once an attack is ready).
Congrats!
It reminds me of an anti-bullying app that simply asked, "Are you sure you want to send this?", which greatly decreased the abuse.
Instagram seems to have the same approach now.
