I have absolutely no idea about this to be honest. I made this for my dad, then made a 'general' version seen here so that others could send a 'card' to their fathers.
The source was provided so that if the pre-made messages didn't appeal, you could modify the text to suit your situation, export it, and then send it onto your intended recipient as a gift.
As long as it's used for this kind of personal, or even educational use, I have no problem with it being shared I guess?
My hope was that some people might get interested in making their own games if they saw behind the curtain and modified a couple of things.
The very first game I modified when I was a little lamb was Psion's Flight Simulator. I broke into the code, changed air speed to 'fart speed' (forgive me!) and played it like that. That moment contributed to starting me off making games, and I guess a part of me hope that someone looking at the source for this might get inspired!
So, I don't know. I guess, use it for educational or personal use? Does that sound right?
Cheers,
