Solve puzzles to deliver mail in an utopian atompunk world. "Pnevmo-Capsula" is a casual adventure game. You will travel to an alternate utopian atompunk world as a small trolley delivering mail. Time seems to have stopped at the break of 1930-1960 years here. The city is connected by a single system of rails, tracks, and pipes. The smallest part of this bizarre system is the mechanical mail.
