One of the things that I imagine might scare some people away, who would like to work on the game, is the idea that it is really hard to make the media for the game. Nothing could be further from the truth, especially for the graphics.
You do not actually need to have a computer program like photoshop, to create digital images. If you can draw, then we can just scan in the images to a computer. We do not need any image editing software at all. It’s very easy. On the other hand, you can also create the images entirely digitally, using photoshop or some other software. It does not need to be perfect, since the image is going to be scaled down in size when it is displayed in the game anyway.
The downside to 2D graphics, is that every image needs to be created manually. So if we have a character running, then we need to create a still of him in every position. That sounds bad, but really, it’s way less work than 3D modeling, animation, and texturing is. Furthermore, for this game specifically, very rough animation is acceptable, at least for prototyping. Super Mario Bros 3, as an example, has a total of 3 static images that they use for mario running, and it looks great. I, the programmer, just need to swap out the images at the right times and the illusion of motion is created.
Again, there are two ways to create sound effects. First, just grab a microphone, even a cheap one will do, and physically create the sound effect you want, then record it. It’s as simple as that. There are many digital programs that can be used to create sound effects. I don’t know how to use any of them, but they do exist.
Programming wise there’s not much to say about sounds. It’s entirely on me to make sure they get played at the right time, and that’s really not very difficult, at least not with such a simple game.
So to recap: If you are good at graphical or audial design, then don’t be intimidated. You can create graphics/sounds. It’s actually pretty easy.
