Pipe spacing

[shiffman]

I think the pipe spacing is still buggy? (See recent commit: a5750bd from @pckerneis.)

I'd like to match the original flappy bird game.

Hey Dan!!! I fixed this issue and updated the code to ES6. As I am not comfortable with gitting, you can access the code here: https://drive.google.com/file/d/1ijRWYSfMuTbvYv1Vd-nUOPuCbJKBoXek/view?usp=drivesdk

If @techiepriyansh his code was submitted in #1, the issue wasn't fixed.

[pckerneis]

Yeah sorry, I went too fast on this one! With @rhbvkleef's fix it should be fine!

Fixed, but it can go beyond the screen sometimes
