Why put so much time and energy into code obfuscation? If the code is visible, then it should be as clear for others as it was for you. Also if that's a top priority for you then you're going the route of the asshole publishers that put more money into DRM than actually making a good game.
Your focus should be on making a fun game. Not making sure that no one can learn from your work or making sure no one can look for cheats in case that's the way they CHOOSE to play it.
Obscuring it just alienates people and pisses them off and drastically lowers their opinion of you, rightly so.
This needed upgrades. It was empty without.
-increase radius of effect of clicking
-increase money per hit
-decrease speed of targets
etc.
