Been playing this for a bit and decided to pay for it to get rid of the ads but decided to look at the reviews first and I'm glad I did. Paying apparently only removes adds for a short period not permanently, the payment may not go through immediately and any attempts after the first one will result in multiple charges to your account, and last, and the very most important, tech support does not respond and will not issue refunds and Play Store says it's not their problem. So essentially a scam.
