I'm beggining with all this gaming stuff, and I'm loving it.
Attached is a "screen saver", just download the jar and double-click it!
I have already successfully made a "Tetris", that is very good, with images and such, but what I really want is to make a scroll 2D, I'm studying tilemaps and fullscreen, GraphicsDevice and BufferStrategy, all of this used in this "screen saver" (just hit "ESC" to quit it).
Accept suggestions, if you like it I can send the code (it's quite well object-oriented, I work with Java).
obs: sorry, I wasn't allowed to attach a .jar
