"Untrusted" Browser Meta-javascript game, edit as you play!

This is a cool/interesting/challenging browser game I came across, thought some people here would get a kick out of it. I don't really know how to explain it, so I will add the blurb from their gitub:

http://alexnisnevich.github.io/untrusted/

Untrusted —or— the Continuing Adventures of Dr. Eval is a Meta-Javascript Adventure Game wherein you guide the dashing, steadfast Dr. Eval through a mysterious MACHINE CONTINUUM, wherein, using only his trusty computer and the TURING-COMPLETE power of Javascript, he must literally ALTER HIS REALITY in order to find his freedom! You must literally edit and re-execute the very Javascript running the game in your browser to save Dr. Eval from this dark and confusing reality!
Overview

The game presents you with a roguelike-like playing environment and a console window with the JavaScript code generating each level. As loaded, each level is unbeatable, and most of the JavaScript is blocked from editing. The challenge is to open a path to the next level using only the limited tools left open to you.

**end**

Basically the level starts unbeatable, and you have to edit the javascript where allowed to change the level and make it beatable. I don't know much javascript so this is also an interesting learning experience. I have been having a bit of fun with it, would like to see how others handle some of the levels.

 

lol, probably, you are thinking a few levels ahead though. It has not added the level checker yet.

You missed the part at the top that said "four clever characters should be enough to erase all their tricks"

Here was my solution:

Spoiler

Code:

/********************
* theLongWayOut.js *
********************
*
* Well, it looks like they're on to us. The path isn't as
* clear as I thought it'd be. But no matter - four clever
* characters should be enough to erase all their tricks.
*/
function startLevel(map) {
map.placePlayer(7, 5);
var maze = new ROT.Map.DividedMaze(map.getWidth(), map.getHeight());
/*
maze.create( function (x, y, mapValue) {
// don't write maze over player
if (map.getPlayer().atLocation(x,y)) {
return 0;
}
else if (mapValue === 1) { //0 is empty space 1 is wall
map.placeObject(x,y, 'block');
}
else {
map.placeObject(x,y,'empty');
}
});
map.placeObject(map.getWidth()-4, map.getHeight()-4, 'block');
map.placeObject(map.getWidth()-6, map.getHeight()-4, 'block');
map.placeObject(map.getWidth()-5, map.getHeight()-5, 'block');
map.placeObject(map.getWidth()-5, map.getHeight()-3, 'block');
*/
 
 
map.placeObject(map.getWidth()-5, map.getHeight()-4, 'exit');
}

 

Yea, I am kinda stuck on the level where you have to pass 12 of them....

 

I don't know if we are talking about the same level, there are 12 of them in a 3 wide hallway, I have to figure out how to get them all to move to the top and bottom of the hallway so I can pass through the center.
