Imagine you're Monument Valley developer ustwo and you have to tweet something like this:
Seems quite a few people have gone back and 1 star reviewed Monument Valley upon update because the expansion was paid. This makes us sad.
Good lord. You already have Monument Valley, were willing to pay $4 for it, presumably loved it, and now when the developers release an update that essentially nearly doubles the content of the game you go all gangster douchebag and actually leave a fucking 1 star review? Word of advice to those whom I'll assume must be living at home and have no concept of financial independence, you'd best be 5-star'ing great content from great developers, because the rest of us who love great games don't want to be punished on account of you running out of credit on the $20 iTunes gift card you got for your birthday.
