I basically did the same, the main difference is, that I don't have a single overlay block, but several (mini) blocks of renamed variables. After having a closer look at your code, I must agree: your solution looks much more elegant!
Unfortunately, I was that short of RAM, that I couldn't use a single block.
I.E. I had to reuse the hi-pointers of the score data AFTER I had calculated the lo-pointers. So I could only use only every 2nd RAM space of that 12 bytes block. And that's easier done with simple variable renaming.
I also had to share variables bitwise, which means the first bits are accessed under a different name than the last bits, because their meaning is totally different. That of course, required a bit more comments than I'm normally used to do ;-)
So, now you know, why I sometimes got confused :)
But using a single overlay area (as long as possible) is CLEARLY the best way to start!
Have fun!
