Overall, this game is incredibly repetitive, much like the flash games that it was based off of, but makes up for it somewhat with a ton of charm. Once you reach the moon once, you will unlock other gamemodes, although they're very much the same thing except with restrictions that make it even more repetitive. You will do this over and over again until you get to the moon, which makes this a little more repetitive than it should be. While you're flying, you can control your spaceship to not hit anything along the way. After each flight attempt, you can buy upgrades to increase its height. Every time you take flight, you get money depending on distance. You control him as he steadily buys and upgrades spaceships to fly higher.
In this game, you control a penguin who desperately wants to fly to the moon. To install Learn to Fly 3, make sure you have Steam installed and then go to this link to install it.
