You are right with AY-music in Menu, so maybe I will make a v 1.1 of the game later, also with faster random numbers generator. I was waiting for the AY music and it came three days too late (I'm lame with Soundtracker).
The game will not work on 16K. I can put it below 32768 without any problems, but the map buffers, instruction and beep engine take too much memory. It is easy to manage to make the buffers smaller using single bits, and remove instruction, but there is still the compiler that puts its heap in high memory. Apart from this, I don't suppose there are many 16K users around .
I expect, most users have 128K at least (not talking about ZS Scorpion 256+ Turbo ot Pentagons).

I noticed too late that automatic translation did not make much sense. It is 30 years now since I learned russian language. Still knowing most cyrilics, but cannot enter them on german keyboard.
