The paper trail of purchasing from a reputable company seems too risky for laundering. The Dev gets a cut of each store transaction, so maybe that's the plan?
It's not the first time where a click game got viral. But it's probably the first time having this much success. What can I say, if people find it enjoyable, go for it. But what I don't understand is, how people cheat with even such a click game, by using bots. It's so funny.
edit:
Despite this seemingly benign gameplay
Calling this a game or gameplay is funny in itself. People are "playing" the dumbest things if they get bored.
