I can't seem to find ANY sample games -- especially those which use keyboard input -- with source files that end EXCLUSIVELY in MXML and AS.
In other words, I don't want to see .FLA files, since I can't do squat with them.
I have Flex 3.0 SDK installed, and I'm content to write programs in a nuts-and-bolts manner. I don't really want Adobe's fancy IDE, since I'm a programmer and used to writing programs with text.
But the free Flex compiler can't do anything with a .FLA file -- and I certainly can't look inside it to see what it's doing. So I can't learn much from Adobe's two examples (Maze and Amoebas).
I found one breakout clone, but it doesn't use keyboard input.
I agree that Flex has a very steep learning curve!
