Sure. I've just given it another run through, and been able to reproduce it reliably.
You just have to redo that level twice, in one sitting (i.e. I played it, and did that level, and then my dad played that level, and it didn't come out)
Simply quitting the game completely, and then loading the game up from that level and it will play correctly.
It should be simple enough to reproduce yourself, just create a new player, play through the early levels, until you get to the bit where the snake captures her. When she's captured, just quit to the main menu, then load your game. From there, she will (or does for me!) get stuck saying "!!!" and no snake comes out. [Although look at the bottom right corner!]
An odd bug, probably caused by persisting variables of some sort. That snake was pretty cool, btw. Nice work on that.
Thanks for that info! I don't know what you've read/tried, but I read a lot on the subject, and found a lot of interesting links/topics on the sites tigsource, and indiegamer. I think that your tip method is tried a bit, but in general no real money is made from it!

Here's some interesting links, you may/may not find interesting.

I'm reading the link on marketing now, haha, I need to.
There is also a discussion on
Donations, which I've linked directly because of it's relevance to your game.
