Glad you liked the game. If you're referring to seeing the same dialogue repeated:
Android players can "rollback" to previous dialogue by simply tapping the left side of their screen. A common mistake Android players make is forgetting about this (mentioned in the tutorial)... so they'll sometimes tap the left-most part of their screens by accident, thus rolling back and seeing the same dialogue twice. Just ensure you're tapping in the center, or on the right-hand side of the screen and you should be good.
