I know that the game elements have a size of 32x32 pixels, but what about the others? How do you make the graphics for the open envelope (you know) and the RockScrenn? What sizes?
And the main background (menu) and all the different fonts and so on.
Could anybody tell me?
I'm working on a project so I need help with the graphics.
Have a look at existing level sets with custom artwork (like those by Alan Bond or Juergen Bonhagen) to see what's possible in custom graphics.
The fixed sized graphics (like screen border) should have the same size, while background graphics (also for envelopes) can have different size and are used to create a tiled background using the specified graphics.
