Hi Captain Jester,
Thank you for commenting. But I thought that the time was over, isn't it?
As ahristov says, you still have time.
I didn't use proguard, but jshrink, a java program I found I don't remember where ;P
ProGuard gives far better results than jshrink
Yes, the files are for the images of the player, I wanted to put some images but I preffered to do more procedural graphics, but they are binary coded into unsigned ints, so If I write it in the .java they would be bigger, wouldn't they?
Your source might be a little bigger, but that will be offset by the lack of file entries in the zip.
I check the wiki, but I didn't have time to revise all the code in order to apply some of the tricks.
One big one from the WiKi is the keyboard controls. That can save you up to 100 bytes, depending on your keyboard use.
