Do you remember Flappy Bird? It was big for about 2 weeks in January and then it disappeared almost as fast as it came, so people won’t blame you if you missed that. Flappy Bird was a controversial game, addictive yet clearly cheap in its programming and design.
Flappy Bird was also accused of plagiarism because its graphics were heavily inspired by the original Mario games, and, maybe more importantly, it was claimed that the game’s creator made $50’000 a day at its peak of popularity. But the author took the game down from the various appstore in order to get rid of the controversy around the game’s popularity vs its actual quality.
