I think this is a great game. It's easy to figure out, the controls are manageable and the viewing scope is easy to direct. The graphics are amazing and the game is lots of fun.
I will agree with other users that there's room for improvements. Things like switching from the current rifles to shotguns, changing the flight patterns and speeds of the bird, perhaps making several different backgrounds, in the future.
I'm not a major gamer, so often the movement sensitivity of my phone makes it difficult for me to enjoy games- I just can't get the hang of the view screen moving everywhere. This game is perfect for amateurs like me. And, perhaps in the future different levels of difficulty could be added. However, I will totally keep playing this game. And I know my husband will steal my phone and play it as well.
