Okay, you guys are going to think this is really retarded, but I discovered this and thought it was kinda funny.
Here's the script, just put it above main:
def i have your cheese
print 'You found my cheese!! Thank you!! Collect your prize at yourwebsitehere.com/cheese'
And there you have it. You can make this anything you want. You can even get real nerdy, for instance:
$scene = nil
Which would turn off the game.
To use this script, just use whatever you put after "def" in a Call Script command. For instance, calling "end_game" in a script command would end the game.
If you wanted to, you could make this do a whole bunch of other stuff. Stuff that I'm too lazy to do right now. You could make sure sophisticated conditional branches.
Yeah, I know this is stupid. Just wanted to post that I figured something funny out xD
