There are not too many roller coaster games online, which is a shame, so we are glad we get to offer you one in the Phineas and Ferb Games category on our website right now, a game which is entitled Coolest Coaster Designer Ever, and which we hope none of you will miss out on playing, because we know from experience just how much fun you can have playing such a game, which has to be obvious from the title, as you will never get the chance to design a roller coaster as cool as in this game. It is fairly easy to do, and we will explain how right now, so make sure you pay attention! Well, the first stage of the part is the one where you design the roller coaster however you want to. You are going to use the mouse to pick up the pieces of the coaster and drag them over the screen, where you can arrange them however you want to, making it look just like your imagination dictates you. After it is done, click on the Ride button, and you will be able to ride the roller coaster that you have just made using the left and right arrow keys, and you will certainly have a great time doing so! Good luck to everyone!
