I programmed my first game!

confirm("Are you ready to play?");
var age=prompt("How old are you?");
if (age<18) { console.log("You can play but I take no resbonsibility. Have fun!"); }
else { console.log("Play and have fun!"); }
console.log("Snow White and Batman were hanging out at the bus stop, waiting to go to the shops. There was a sale on and both needed some new threads. You've never really liked Batman. You walk up to him.");
console.log("Batman glares at you.");
var userAnswer=prompt("Are you feeling lucky, punk?");
if (userAnswer==="yes") {console.log("Batman hits you very hard. It's Batman and you're you! Of course Batman wins!");}
else {console.log("You did not say yes to feeling lucky. Good choice! You are a winner in the game of not getting beaten up by Batman.");}
var feedback=prompt("Rate the game 1-10");
if (feedback>7) {console.log("This is just the beginning of my game empire. Stay tuned for more!");}
else {console.log("I slaved away at this game and you gave me that score?! The nerve! Just you wait!");}
What you think about my game? It`s of course very simple, but I only started to learn programming six days ago :)
