"When making games you need to worry about many different things which can make it look intimidating at first:
- Game development: programming the game logic.
- Game assets: images, artwork, sound, animations.
- Game content: levels, story.
There is an easy way to take one of the three out of the equation for when you are just starting, which is to use plain rectangles as artwork. In this manner, you can work on the game mechanics right away, without having to spend money or time in making the artwork. Moreover, using rectangles at first gives you a better idea of your artwork requirements."
