History-wise, when was this game released? Symbian devices were more popular in the late 2000s to early 2010s, so maybe Dragon Bird is from that time. If it's a clone, it might have come out after Flappy Bird's rise in popularity, like around 2014-2015. But Symbian phones were already declining by then, so perhaps it was a nostalgic attempt to port such games to older devices.
