I'd say many people neither have python installed, nor want to install it just to play a game 
And I don't want to
fight withinstall mono and XNA but you don't see me complaining.

But kidding aside, I think I've never got py2exe to work. I don't remember what happened last time I tried so this could be very inaccurate. But I think I needed Windows (or a component thereof) to begin with. On the other hand, if you can generate an .exe, I'd be happy to link to it.
I can't guarantee the submission form will work tomorrow...
Please save me some work and submit it now, will ya? <3
I have the same problem as before. After submission, the files in the forms' files are removed and each of the textfields is a little bit more escaped (so if I hit submit a few times in a row, I'll get a long chains of \\\\\\\\\\ and some \r\n).
From the headers, it looks like its choking on the .png files? But that could also be my viewer. I'm also surprised the logs say nothing since I'm quite sure a POST request is being made (and I think the server even responds).
Also, do know why the file
http://games.mylittlegamejam.com/game/js/vendor/modernizr-2.6.1.min.js is requested but missing?
Using the new file gives this error:

EDIT:
When I downloaded the latest stable version of the 2.x branch, I get this:

I use Python 3.3 I just downloaded from here: http://www.python.org/download/releases/3.3.0/
Thanks again for reporting. Ah yes, Python 3.x is not backwards compatible with Python 2.x. Can you try this new one (attached)? This time, it actually has a good chance of fixing the problem.
I won't respond any more today but I'll check back tomorrow.
