This badge is only available for students who (a) have used Construct 2 to create games in the mobile gaming course or (b) have already completed the "Basic Game Design" badge for the web design course. To earn this badge, you will create a new game from scratch using Construct 2.
Since platform games are the basis of the "Basic Game Design" badge, you cannot earn this badge by completing a platform game. You must create a new type of game, and -- in the process -- you should be exposed to new programming concepts. Possible game genres might include: a space shooter, a role-playing game in which a character gains levels and abilities, a tower defense game, a puzzle physics game, a tile shuffling puzzle game, a political trivia game, a racing game, or some sort of hybrid game.
In designing this new game, you are not required to create the game entirely from scratch. In fact, you are encouraged to create the basic template for the game by following along with tutorials in Construct 2 development manuals or on the Scirra site.
