differences from other games are that birds may still perform their chosen abilities a split second after colliding with an object. the millennium falcon is used instead of the "mighty eagle" found in previous games. when a certain number of stars are earned, the player gets a reward. it can be either 5 millennium falcons (an item that may be used during normal levels to try to earn badges) or access to a golden droid level. there are additional bonus levels if the player manages to hit golden droids in selected levels. on june 13, 2013, power-ups were added.
