Amazing game, smooth gameplay and great graphics. The game is fun, and teaches you along the way. Notes:1 Pay attention to whats on the screen. Especially in later levels where alot happens 2 The game doesnt back up save data, so if you unisnstall it you will lose your data.(Unless an account is made) Finally 3 The games ment to be challenging. Also try looking closely at when your tapping the screen, to make sure your tapping at the right time
