I don't understand well this . Or well , want to make sure this is what I think.

If my game is more than 32kb but zipped is 32kb or less is valid ?

Also , no strange compression true ? no rar or ace or 7z ?

Yes it is valid if you can zip it to 32k or less. 

Let's keep it to zip so people don't need to install 7zip or any other software.
