Alright, this is pretty much a flappy bird variant (which itself was done prior to that, as you state yourself on that helicopter game). Not necessarily original, but building on a proven concept is totally fine.
What I dislike is that there is not much building upon the concept happening, as there is nothing but evading floor and ceiling, so the game didn't really hook me up for very long.
Music and sound work well with the overall feel of them game.
I encountered a game breaking bug multiple times, where the floor would just go up to the top of the world, forcing failure (check screenshot). Happened on different distances, so not linked to that.
