I have one badge as well but my Snivy is only on level 14. However, I have trained my Lillipup to level 14, too and my Panpour's level is 11.
I let a friend of mine try the game yesterday, but I had hard time because he's just 7 years old and even too helpful. He'd have played the whole game through for me if I hadn't invented something more special to do. Anyways, he beat some trainers so now I cannot say I've played the game totally on my own. Also, he accidentially pressed wrong buttons and bought me like 100 mail. We sold them back but I did consider starting the whole game all over again.
