Learn to Fly Idle
Learn to Fly is a game where you had to make a penguin fly as far as possible and which was one of the precursors of upgrade games.
He's back today to surrender to the idle fashion, these games like "Cookie Clicker" where your only goal is to increase a unity to infinity.
So help our little penguin to destroy various frozen targets, in order to always make more money and reinvest all your profits in upgrades.
