Kudos, that looks very good for a high school coding project (both visuals, and the code looks very well structured).

I feel like half of all software devs started out like this - coding their own game.

Crazy to imagine that no one will build their mental muscle like this anymore.

I sure learnt so much analytical thinking, debugging, problem solving and banging my head against a mental wall until the wall yielded through passion hobby projects like this. Wouldn't have been the same just saying "Claude, make [insert game here]".

I think "no one will build their mental muscle like this anymore" is a bit defeatist. I am still pushing myself coding new and challenging things by hand, not using AI at all for it.
