Game Develop is a free creator software, allowing the development of any kind of 2D games. No knowledge is required, all the development process is made thanks to a graphical user interface, with all editors integrated. The creation under Game Develop is thus entirely "visual": creation of objects, image insertions, objects positioning. No line of code has to be written, Game Develop uses indeed an event system based on conditions, which have to been filled so as to execute actions. Game Develop is not limited to one kind of game: you can create for instance platform games, racing games with full 3D buildings. The integrated development environment of Game Develop provides to the user a complete control on the game. Game Develop can be used by everyone, from the beginner to the experimented developer. Graphic designers can use Game Develop so as to give life to their creation, developers can make easily prototypes.
