Blackberries and the sudden popularity of Caro

I’ve written before how the popularity of games always surprises me, how I never know in advance if a game I upload will be downloaded a lot, little or not at all. After a certain time the number of downloads usually stays fairly constant. If a game that has been up for years suddenly gets a boost in popularity, there is usually a specific reason, just as now with Thu Nguyen’s Caro.
