Needs work. Looks like someone's first game (not a bad thing). I'd suggest making the camera a lot closer to the bird/circle, I don't understand why it has to be this zoomed out. Gameplay is pretty simple, I found it a bit confusing that the bird moves around in a circle because you've got to estimate where it is and it's a lot less intuitive than Flappy bird (which I assume was the inspiration for this game). Despite it it's still original, and performance is good.
