In short, there are just a lot of things going on in Learn to Fly.
Learn to Fly combines a lot of different skills, from the strategical upgrading that players must efficiently do to the skills that are required to fly as far as possible with the upgrades that they are given. In contrast, Learn to Fly Idle is about automating upgrades to your canon's power, speed, and more to get a high score and shoot down snowmen. In the original Learn to Fly, players are trying to help your penguin get as much distance as possible to break through the giant iceberg over one mile away. The overall goal is different in the two games as well. In Learn to Fly Idle, players are shooting cannons and destroying objects like snowmen, instead of shooting themselves off of a snowy ramp and trying to launch for as distance as they can. What is the difference between Learn to Fly and Learn to Fly Idle? Although Learn to Fly has a simple and straightforward concept, it quickly became a staple of Coolmath Games and has stayed as one of our most popular games on the site over the past decade. Learn to Fly came out in December of 2011 and was released by Light Bringer Games. Both Learn to fly and Learn to Fly Idle are playable on Coolmath Games.
