I am writing a 2d game, I have designed the characters but I would need backgrounds, i'm looking free cavern backgrounds for a free game, advice ?
thanks in advance
Well, there are several options here:
You could do the most safe and copyright free way possible, and make it yourself, but this would take quite a long time if you wanted a fairly decent one, and by the sounds of things you don't seem to want to do this.
Try searching the web for 'copyright free cavern backgrounds', or find a site that gives them out, and search in their custom search bars instead. This is one I usually go to, but there are many others: http://www.freedigitalphotos.net/images/Backgrounds_g162.html
Anyway hope this helps! And it doesn't tell me below, and I'll see what I can do!
