Screenpacker compressed the game exactly to 949 bytes, the max number of bytes to load in 1K.
So my free codeable memory did not get smaller.

Passenger appear on the map and can be pickup.
Only thing missing is chasers and some gameover.

I reused the ghostmovement from K-Man for the chasers but due to the layered roads this was not working.
Finally I have chasers moving.

Hi Johan,
Your code optimization work on the zx81 is impressive.
Thanks.

Nice game of course.

It seems to me that organizing a kitty on this forum to offer him a 16k extension would be good.
1 kb is enouth.
Thanks angain Jhoan.
Note: TS1000 = 2Kb !

Sorry !

I had a zx81 and a ts1000 when I started coding the first 1K hires games.
After my TV died after almost 50 years I stopped using real hardware.
I donated my hardware to Ben Versteeg from Bytedelight.

I have some extra points in 1K but I also found how the game can end in a bug which I need to solve
but code is tight.
