Scratch

I've put together the starting point for a game project...

it gives you:

1) An intro screen, with it's own background, and with a game title sprite, a set of instructions, and the 3 difficulty selection buttons. While this is being displayed, a sound will loop in the background.

2) A 'play' screen. This is where all the action should take place. It has it's own music.  Currently there's just a button to 'end' the game, to show the next screen...

3) Game Over! The player has run out of lives. Plays a fanfare if the hi-score is beaten.  Another music loop will play.  Re-displays the difficulty buttons for quick replay.

Obviously all the images and sounds are just 'placeholders' and should all be replaced by nice graphics and tunes 

The sound loops and changes of background are handled by scripts on the Stage.

The key variable is 'Game State' which can also be used to decide when sprites should be hidden or displayed, when loops should exit etc etc.

Please remix it to add even more features.. I was going to add in bullet sprites, but I think maybe there should be a few specialised 'skeletons' (ie. 'skeleton platformer', 'skeleton shooter' etc) and leave this as a generic 'base skeleton'.
