GameMaker

GameMaker is an integrated game development environment that runs on the PC (a somewhat
older version is also available on the Mac). It allows you to add and create  animated  sprites and
background images, add sound effects and fonts, define object behavior, and design rooms in which
the action happens. It is very easy to use because everything can be done using a drag-and-drop
interface in which you assign actions to events for objects. But  GameMaker also has a full-blown
programming language incorporated with over a thousand functions  that let you control every
aspect of your game. GameMaker is primarily meant for 2D games, but it also includes functionality
for 3D graphics.

GameMaker is used all over the world by hundreds of thousands of amateurs, in schools, and by
professional game developers. Games created with  GameMaker have won important prizes,
showing its power. You can download the free  Lite  version of  GameMaker from the webpage
http://store.yoyogames.com/browse?platform=9 to get an idea of its possibilities. You will create
fascinating games in no time.

Not every game created in GameMaker will automatically run on the iPhone or Android. You have to
take certain constrains into account (e.g. related to the screen size and controls) and some features
in GameMaker are unavailable on the iPhone (e.g. multi-player and windows related functions). All
of this is outlined below.
