For being a "Flappy Bird Clone", this honestly is a solid little attempt. Controls work, and it plays nicely. I personally like how in your version, it's not an immediate game over if you hit the pipes. At the end of the day, you were able to put this together; you put forth the effort to make a thing, and you did it!
If you make any updates or improvements, I'd definitely come back and see what you end up doing, as I feel like you have the basic core mechanic down pat!
Well done!
