I've seen a few Flappy Bird type games, but sometimes they ended up as frustrating as (I hear) the original was in their role reversal.
This was not one of those games though (though I'm still frustrated at how bad I am). The classic music suits the tone, the art was very welcoming and cohesive, and the idea fits the theme nicely.
I'm glad you made it clear the bird wasn't moving as well, since my brain wouldn't have assumed that otherwise!
