cat game ???
        gems
        diff kinds of cats, and food

	swap cat with food = cat chomps food.  minor points for food vanish.
                food:  dry food
                food:  wet food
                food:  cheese
                food:  ham

	cat gets fatter ?

        line of diff cats = cat parade.  medium points.
        line of same cats = big points!
        line of cats with goat at the end = get rid of lots!

	any parade gives you more moves.


	game params:
		# of moves limit
		score

*bugfix :parade movement bounces up down!
*bugfix: another bug with anyvalidmoves() - offscreen things showing up as having moves
*initial code to make grid size bigger on later levels


allow specifying gridw instead of gridsize

make levels default to gridsize of previous one

getting cats with x not aligned to gridx!

finishing a level with no stars should be gameover ???




special things - 5% chance of any 
{

	white cat - 
		move cat on to it to FIGHT.
		destroy 9 in a block around.
		pow pow cloud.

	mouse toy - match 3 to explode everything ?

	special food that lets you turn corners?

	brush - 

	doona - hide under it to avoid llama /sun effects ?

}

more goals:
	form x parades of length y
	survive x moves

sounds:
	chomp
	catparade (can-can ?)
	indy theme - title screen? 
		(if so, make title text indy themed too)



make path part of game object
make things part of game object

ideas:
	llamas don't appear after the start, you just have to get rid of them all?
