GameMaker: Studio (originally named Animo and later Game Maker) is a proprietary game creation system created by Mark Overmars in the Delphi programming language.GameMaker accommodates the creation of cross-platform and multi-genre video games using drag and drop action sequences or a sandboxed scripting language known as Game Maker Language, which can be used to develop more advanced games that could not be created just by using the drag and drop features.
