flash games
 

this might sound a little naive but can a guy that creates flash games make any money from it?

I saw someone put up a demo version where there is only 1 level and to play the others you have to pay online, is this the only way?

heya zester :) good question

Sure, you can make money. How much depends on a lot of factors.... ;)

what factors other than the flash game itself?

usually they sell their games to big sites or companies - that's a good for adv
