Dong Nguyen from Vietnam has taken to Twitter to deny any requests from press for interviews - and to deny lucrative marketing deals with US retailers.
Here are some of the things he's said so far:
1: His success is "overrated" and he didn't want it to happen:
@joekloc Hi Joe, I think press should give my game some peace. Its success is really overrate! I'm sorry, I refuse to answer questions.
2: Journalists are hounding him in his own country:
@sherpa I'm trying hard to do but things are out of my control. Press people are looking for me right here in my country too!
3. He's turned down offers of 'Flappy Bird' merchandise:
@kreckinfl Well, I think Flappy Bird should stay only in mobile games world.
4. He's not bringing the game to consoles:
5: His success is "out of control".
6. His high score on Flappy Bird is 150.
@kunpaaki Over 150 :-)
7. He's a philosopher:
@craigjbarber The tip is no tip. There is no book, do what you think it right.
