How long does it take to beat Zeus on mythology island?

It depends on how many times you play the level. It took me around 5 minutes on, like the 2 try. you have to avoid all the things he shoots at you and shoot him. you also have to colect the floating pink clouds in the sky to regain power. and when zues is gloing, you gatta collect ALOT of clouds because he will throw 5 orbs at you that take away lots of your power! HOPE IT HELPS! :)
