>Also, I was confused by the switch statement that took a boolean and had a case for true and false. Why didn't you use an if statement?

You know, it never occurred to me to do that, but I think there may be times when that would be a clearer idiom than an if statement (as long as you put "default:" immediately after "case true:"). I always feel like the order of clauses in an if-else gives a sense of privilege to whichever case is handled first, but there's less of that sense with a switch statement.

In particular, I think it might be a good alternative to conditionals on non-boolean arguments. For example, instead of:

    if(countDown) {
        countDown--;
    } else {
        blastOff();
    }

You could use:

    switch (countDown) {
        case 0:
            blastOff();
            break;
        default:
            countDown--;
    }
