The crack doesn't actually do anything other than create a text file, but it's deliberately made to be as terrifying as possible. I was worried that some people would absolutely refuse to use it, and the game isn't really winnable without it, so that's why I included the console commands in the readme file.
The optimal number of guns is 4-7. Above that it gets kind of boring, and above 20 it starts glitching out. I think what's happening is the bullets are either hitting each other or hitting the guns. I didn't really put much time into trying to fix it. I also didn't bother with object pooling or other optimization, so too many guns is probably a performance killer.
I prefer spamming missiles, though.
I wouldn't count on the CD Audio feature working fine. It worked in my (limited) testing but it's incredibly hacky. Music is actually played by opening VLC in the background, and stopped by killing the VLC process.
I feel this is a better game than TWAT, but I also feel that it's a weaker entry for SBIG Jam if that makes any sense.
