“greenTech+ was the wining entry into the YoYo Games competition back in 2010, and has quite an oddball history. The game is designed as an old computer game (with the freeware version emulating a CRT-like stretch display), where you must lead clouds of pollution into factories for cleansing. It is fairly short, yet tremendously difficult. It is, in fact, one of my own favorite games to play, as it’s one of the few games where I don’t rely on logic or patterns for users to complete- it’s just straight up old school gameplay at it’s simplest.” - Vertigo Gaming
