A recording of a speech by Dong Nguyen, the author of Flappy Bird, from the Gamelab 2014 conference held last month in Barcelona has appeared on the web. The guy thinks that others should not develop games the way he did Flappy Bird.
The second time the “script” will not work.
“Flappy Bird has set a dangerous precedent, because what I did was something like magic, I did not expect such results. If people try to do this again, they will fail,” Nguyen said.
He advises young developers to make games in their free time from their main work, which should be “good“.
