I seem to just get a screen of green pixellated lines. Doesn't seem playable right now.

Edit: Oh wait, it is a bug, I'm now seeing this broken state on a different computer.
It's not a bug, that's what the game looks like. :)
It can be pretty confusing at first, if you're stuck in the first level, start by going to the right. And if the arrow keys aren't responding, click the game with the mouse to focus it.
Oh, and the minimum resolution is 1280x960.
My apologies, you were absolutely right.
The game had a critical bug on some browsers and didn't work at all, luckily I had the same issue at my work computer.
I found a way to fix it, it should work now. :)
If you're interested in the details, the problem was that my maps were PNGs, and it seems some browser versions change the colors slightly, which made the maps undecipherable. I changed the files to BMPs and it's working fine now. (and is even a smaller file size)
