I'm not really sure what I'm going to price it at. I want it to be less than a deck of cards, maybe $1.99ish? But I'd also like to figure out the best way to make the amount of work I've put into this (over a year of changing/tweaking/perfecting.)

I'd also like to know about my security options for hiding my source code

Anything else that comes to your mind would be helpful.

Here are some screenshots to give you a pretty basic understanding about the game/design: http://imgur.com/a/6vKIF

Thanks for your time!
