I do not understand how this game works. All I get is a lot of squares (Opera, IE9, Chrome)

I get the cop on the left and "squares" in the tab. While a cute idea it is not all that interesting as it sits in a single tab with Firefox. So the whole display is very tight as I have eight tabs.

Then there is the whole, just spam spacebar for the win.

What version of Opera and Chrome? Opera 12.01 and Chrome 21 work - this is what you should see in your title bar: http://o25.img-up.net/screen1239.png

I have chrome 21 and I just see squares

edit: On windows 7 64 bit

In Chrome 21 (Win7-64) I only see squares moving in title bar In FF14 (Win7-64) the characters show, but are black.

In Chrome 18, Opera 12.01 and Firefox 16 I also only get boxes. All on Ubuntu 12.04.

Chrome 21, Windows 7. Only see squares.

Firefox 14, Linux. I see only squares.

it's all (unicode) boxes, no graphics.

chrome 21.0.1180.79 + ff 14.0.1 on mac os x

I use chrome 21.0.1180.79 on mac os x, and it works fine here.

I think it's because the author uses apple icons, so it doesn't render at all on windows machines.

Yep just squares here for a few seconds and then game over (Chrome 21.0.1180.79 on Win7 x64)

Doesn't work for me either in Aurora (Firefox 16) or Chrome 21 beta (on Windows 7).

Fantastic work - I love these kinds of zany hacks. Though, this should be combined this with some "Defender of the Favicon" magic for extra gameplay options! http://www.p01.org/releases/DEFENDER_of_the_favicon/

If anyone else is wondering how the characters are generated:

  states = {
    // policeman
    "0": decodeEntities("👮"),
    ...
    // octopus
    "3": decodeEntities("🐙"),

    // explosion
    "4": decodeEntities("💥") 
  };

That's weird, I'm fairly sure JS strings are Unicode.

As lovely as it is, this will probably only work on Mac as both Windows and Linux don't support Emoji

And only current Macs to boot... it doesn't work under Snow Leopard.

EDIT: Looking at his home page, it’s pretty clear he is designing towards tablets first, and other machine types second…

It is rather confusing with just a string of boxes in the title bar.

I also only get squares. But if you hold down the space key you get endless amount of points :)

Nice idea, but I can't help being reminded of the old days of JavaScript, where the status bar was abused for scrolling text marquees.

have no title bar in chrome :/

It works on the tab bar in chrome.
