Interesting bug.
No, explanable!

Dfile is set BEFORE the HIRES-screen and in 16K expanded and so creating the error.

Error was created by reading inaccessable RAM in 1K which was there in 16K.

I like the bug because it shows that it is a true 1K game.

A really cool game for unexpanded ZX81.

I have found the bug why the program didn't run on a 16K and did on a 1K.

In fact it was pure coincidence that the code DID RUN on a 1K ZX81.

To solve the bug I needed more room for the stack (which I did not have) but thanks to the development of further games I was able
to alter the code with a trick used in later games and so creating just enough room to implement the bugfix.

I also changed the minimal distance between platforms back to 50 in stead of 60 and so using the full buffer again with max 4 platforms on screen.

The bugfixed version will be part of the pack.
