. I've played Smuta last week, downloaded it from here. It seems to be some sort of shareware version, though. It has only four levels -when you beat the fourth, a message appears saying, in Russian, that you should buy the game-. And in the main menu, there is a demo option -демонстрация- that shows new levels, enemies and weapons from the full version.Not a great game, though, but I enjoyed it.
for the info, I'll change the description on it next update.
