Nice job dude! The pixelated look with 3D objects looks pretty cool. I suck just as bad as in flappy bird but it definitely works well. As for feedback, I think the gravity of the ball may be a bit more floaty than it was in Flappybird (if I remember correctly anyway) which makes it easier to fly off past the top of screen. Then again, flappybird was hard to control too so that's all relative I guess. :P
Keep it up man!
