The Battle for Rust Knowledge Supremacy

Are there only four sets of questions? It would be nice if the game would show some kind of "You got them all, now invite your friends!" or similar instead of simply looping me to loop city without explaining anything.

Awesomely ludic! Do you know similar things for other languages or frameworks?

How to change location on the map? Stuck in struct town. Nice gotcha with vec![0usize, 3] though.

Unfortunately, the UI is broken. After awhile, the "Next" button stops working.
