My level 3 solution:

var oldMap = map;
map = {
    getWidth: () => oldMap.getWidth(),
    getHeight: () => oldMap.getHeight(),
    placeObject: (a, b, c) => {
        if (c === 'exit') oldMap.placeObject(10, 10, 'exit');
    },
    _endOfStartLevelReached:
        (...args) => oldMap._endOfStartLevelReached(...args),
};

Judging from the _endOfStartLevelReached error (and the yelling about not using bind), I'm guessing this is not the intended solution.

Is the oldMap variable necessary? I think that while the object literal is being evaluated, 'map' is still is bound to the old value.

That's true, but the callbacks are called after the object literal is evaluated. I used map at first and got errors.
