The gameplay itself is really enjoyable, it feel like flappy bird or some other flash game. But I agree with another comment that the celling closing in shouldn't be a thing. You cannot do anything about it and it just force you to die at around 1200 score, which doesn't take long to get there at all. I suggest that it could close in just to some degree as a way to increase difficulty instead? But other than that, the main mechanic itself is nice and feel very smooth to play.
