Well, what else to say? Thanks to ThunderJury for the work, and to Mark Overmars for Game Maker 8.1.
The first version of this game was made for the "Gaminator 9" contest on the "Gamin.ru" site, which was later transferred to "Gamin.me" and right now is unavailable (but promised to be back in august 2015). Theme of the contest was "White Silence", so that's basically what the game "is" about. However, it's a kind of a killing whiteness... or a killing silence?
