I have The Void but have nothing looks like Tension or Turgor.
(I have tried all language options.)
Maybe it is an old bundle or giveaway?
The game was updated with a Polish version a while back, which turned out to be the original Tension. The German, Russian and English versions are all The Void.
Isn't Tension/Turgor the Russian / Polish name for The Void? i.e. the same game with different names depending on where it was released
It's slightly complicated.
-Turgor is the original Russian release of the game.
-Tension is the Polish release of the original.
-The Void is the German/English release and also a remaster of Turgor/Tension that also had a Russian and Polish release. It has a different story, reworked graphics and a different gameplay feel.
The original Tension/Turgor never saw an English release, but had an English patch for it made be a member of the Ice-Pick Lodge team.
The Void and Turgor/Tension are different perspectives on the same idea and very different experiences. In general, Tension/Turgor is more esoteric and open-ended, and The Void is the tighter experience with more polished mechanics. Opinions differ on which one is better and it's worth playing play both if you like either one.
