Earlier quoted context omitted.

Is there anything else you could modify to change what the raft does?

Yes...but I can't do it at an intelligent time.

This is fun. But I have one wish. Overwrite console.log() so it logs onto the website and I don't need to open firebug :) Edit: I think I solved lvl two to four all the same way. Not sure if that's intended. But I also don't want to spoil it for others. Edit 2: This worked again at lvl 6, so I'll assume that's a bug. Click this pastebin for spoilers: http://pastebin.com/yfhDhE7P

Good catch! We haven't been checking yet for tampering with functions, but we probably should. Don't think of it as a bug so much as a cheatcode you discovered :-)

    map.pO = map.placeObject;
    map.placeObject = function(x, y, w){
        return map.pO(x, y, w=='block'?'empty':w);
    }

This worked for the whole first chapter for me (and has some obvious further applications): startLevel["constructor"]("m", "console.log(m);" + "var old = m.placeObject;\n" + "m.placeObject = function(x,y,t) { \n" + "console.log(t);\n" + "if (t === 'exit' || t === 'computer') {\n" + "console.log('adding' + t);\n" + "return old['ca' + 'll'](m, x,y,t) }};")(map); EDIT: I wonder if you could wrap the user's code in, e.g.…

nice! similarly, var oldPlaceObject = map.placeObject; var newPlaceObject = function(x, y, type) { if (type !== 'block') { map.placeObject = oldPlaceObject; map.placeObject(x, y, type); map.placeObject = newPlaceObject; } }; map.placeObject = newPlaceObject; was my solution to multiple levels ;).
