Yes. Adobe have released a software development kit called Flex to compile flash games. From what I can remember it uses xml
and actionscript files and there is no GUI (compiling is all done through the command prompt)
Give it a shot if you want but Unless you are very familiar with action script you might find it difficult to start learning like this.
I would download the adobe flash CS5 30 day trial first to get us to the language then when you are comfortable move onto Flex.
If all you want is a game that can be run from the web and you have no experience with flash then you could start with Java. You should be able
topick up the basics quickly and be making simple games in weeks.
Hope this helps you :)
