I can only help you out with one thing, highscores (program writeback). 
Just define a byte or word and change it.   For example for a high score
from 0-255 do

If you don't understand the below, basiacally, you create a byte using
.db or a word using .dw, load that to hl, and use (hl) to store something
to the location.  Seeing how difficult it for me to express my ideas, you
can see why I'm not making any tutorials. : )

You can store anything you want to the program which I think is really
cool cause it's like a permanant variable that can't be overitten
accidentally.

I just got an idea, I'm gonna make an ASM program that let's  you store
and recall variables to/from it in basic so tyou don't have to use user
variables and lists.

; For displaying the high score

DisplayHS:
	ld	hl,HighScore
	call	_dispHL

; For storing the high score

StoreHS:
	ld	a,(currentscore)	; If you stored the current
score to 	ld	hl,HighScore	; (currentscore)
	ld	(hl),a

; This area of the prog would acctually change after you got the
highscore

HighScore:
	.db	0		; Or you could use .dw for a higher
high 					; score capacity
