This is one of the games
that Dmitry Pavlovsky wrote in the early 80s on an Electronica 60
and that were later ported to the PC by Vadim Gerasimov. They worked
in a team with Alexey Pajitnov; since the latter than decided to
abandon all the games they had been working on except his own
Tetris, AntiXonix was never published, just
somehow distributed for free.
AntiXonix is named after (or against) Xonix, an obscure Qix clone which has given its name to several others, but which, for the longest time, I never got to run on anything. It was one of the very few games that manage to crash DOSBox, but this has been fixed as of version 0.73, and you can look at Xonix DOSBox screenshots now.
AntiXonix, au contraire, always ran on pretty much anything, except for the speed, so best play it in DOSBox. One problem is that I found the controls somewhat unresponsive, which, given the way the game works, has disastrous results. But maybe that's an intended part of the gameplay.
