Happy Warlord

Hi, I've only been playing this game for about a month, and this is my first time buying kobans. I was wondering if anyone would be able to answer these questions, as I have a few concerns that I want to put to rest. 1. My main concern is that I don't want to be scammed. Is anyone able to verify the legitimacy of this game? 2. Is it possible to use payment methods such as paypal to pay for in-game purchases? 3. If I was to purchase something from the game, would it show up on anything like a bank statement, or will I get some sort of confirmation email after, etc I'm sorry if I seem paranoid, but I'm genuinely worried about being scammed, or worse. If anyone can answer these questions, it would be greatly appreciated, thanks!
