This was an interesting angle on the classic! It's ridiculously difficult though, I can't even seem to get past the first obstacle... though I feel I should be getting past it all the time. Oh, spamming space bar works wonders! :P Maybe you could go for a third-bird view, where you see the bird slightly over its shoulder so you can see how close you are to the obstacle; how to best avoid them? And also maybe add some upper limit; more visual scenery. Idea's great though, keep it up!
