Haven't played much flappy bird so this is fairly fresh for me - I enjoyed it!
Some thoughts:
Worked fine on my ipad.
I really like the background art style. Also the bird crash animation

Disembodied stripy barriers coming from the sky is a bit weird - would tree branches or alien tentacles make more sense? Also it's odd for the bird to die from flying just into air at the top of the screen - couldn't he just fall back down into view again?
The difficulty seems OK ..... except for ...... restarting from the beginning after each death! I'm done with the game now after 10 mins mainly because I don't want to do the first level again and again. I'd be happy to play a lot more if it wasn't for that. A 3-lives system would be maybe a bit old school but nothing wrong with that, or it could have checkpoints. Having said that I have slow reflexes so you may have it pitched just right

Is there some way to shoot corn cobs diagonally like in the screenshots? I could only shoot horizontally.
Gameplay-wise, well I'm guessing there might be laser beams and stuff later, or homing missiles which would explain the screenshots! But at the moment it's not drawing me back...
I can see the attraction, the "purity", of keeping strictly to one-tap control, but it feels really limiting to me. Could you hook something onto double taps or swipes? It would still be playable with one hand on the phone then and there would be more range of expression for the player. Again maybe this comes in later and I never got to see it?
Cheers,
Rich.
