UPDATE 4/1/21: In one of the last news stories I wrote back in 2020, I mentioned below how Monument Valley studio Ustwo was planting a tree for every copy of its new game Alba that was either downloaded or sold.
Well, a couple of weeks, one broken radiator and several plumber visits later (how was your Christmas break?) there's some good news at least on this front.
Ustwo has now said it has ensured over a quarter of a million trees will be planted - 276,490 at the time of writing - which presumably also equates to the number of times Alba has so far either been bought on PC or downloaded on iPhone, where it is part of the Apple Arcade subscription.
