Help! – Zen Koi Classic Review

So, I downloaded this game to play for myself. It’s really fun and the graphics are really good. Unlike other games, I can’t get bored. But one day, my cousins decided they could just play on my account and now I’m already at level 10, when I only got to play ten minutes. I tried deleting it and telling them no, changing the passcode, and hiding the iPad, but they keep on finding it! When I deleted it, I got it again in hopes that it would start over, but it didn’t. Is there any way that I can lock a certain app with a passcode or delete the actual data? I know that data save is useful, but it is really annoying in my situation. Please reply! But don’t change the gameplay!
