Quite a stretch to call this Flappy Bird. It’s more like: trademark sniped and name being reused to snag unsuspecting users looking for the original game.
New game by the same name is obvious cash grab. Of course it would be. Its entire purpose is name squatting the real Flappy Bird. They even went so far as to name themselves The Flappy Bird Foundation with no real relation to the titular game, for the express purpose of sounding official.
You’d be lucky it doesn’t come with malware because the entire premise is fundamentally a scam.
