Mega mobile hit Flappy Bird made a surprise return last week but something seemed off. Despite first-person language using “I” in the announcement, there was no mention of the twitchy arcade-style game’s original creator.

The Flappy Bird Foundation then acquired the rights from Gametech Holdings. The group also filed in opposition of Nguyen's trademark in 2023, per The Verge. Related: First Patient with Neuralink Brain Chip Can Play Video Games with His Mind: 'It's Crazy'

Last week, The Flappy Bird Foundation announced a game called Flappy Bird. But while the group has been framing it as the triumphant return of a classic mobile game, Flappy Bird’ s original developer, Dong Nguyen isn’t calling it a comeback — in fact, he says he’s not involved at all.
