Quoted from Nokoro:No. But for some reason I have this irrational thing about apps. I'll pay $4 for a cup of coffee, thousands of dollars for a pinball machine, but don't like paying 99 cents for an app. It's stupid and makes no sense. I'm probably conditioned with all of the free apps out there. Anyway, I paid for it in this case. It's pretty cool, and you can't really get very far without paying.
Sign up for Google Rewards surveys, if you're on android. Little 15-20 second surveys a few times a week about places you've been. 20-80 cents per survey. I pay for almost ALL of my mobile game content either partially or in full with credit from these.
