I was arguing with my best buddy today about it. I consider that "Learn To Fly" is waaay easier, and does not need much attention. I seek difficulty in games, I like to beat them as a principle, as a core of my geekness. "Pirate launch" has lesser achievement and upgrade options. "Pirate launch" clouds are not making funny faces. But game needs your attention, control, grip. Getting to the end of level in "Learn to fly" could be done with eyes closed. Just go in wawes left right left right left right with amplitude needed. Whole process is boring. Nothing differs, nothing happens. You just fly, listening to boring music.
it has much epicer music. the ending is a lot funnier. and ya it requires constant attention otherwise you go splat into the water.
learn to fly is cool in all but pirate launch is better.
plus there is the element of luck. learn to fly... there aint no luck just upgrades.
pirate launch your like (when your skidding across water), c'mon i need a bomb, i need a whale... no a shark! or no an island! it has more luck in it and it just gets you thinking iam gonna lose iam gonna lose... then you get unlucky enough to stop right infront of a whale or bomb and then the day is over or you get lucky to hit the whale or bomb and get going!
