In order to develop your game, you will need assets (e.g. images, sounds, etc.). This page lists a number of free resources where you can find assets, as well as free tools you can use to manipulate or develop your own assets.

Of course, you could also just go to Google and search for images and sounds. But if you do, you need to be especially aware of whether you can legally reuse the content - remember to respect the rights of others.

In addition to the resources below, this website offers a number of additional free resources.
