Modify The Impulse of the bird

[hadyhelal]

First of al thank you for this open source project I learned a lot form it😄.

I played the game as a user and found out that it's pretty hard to get a normal score, actually I can't pass The first block and this annoyed me(as a player)!

I looked at the code and modify this line in GameScene -> line number 211
bird.physicsBody?.applyImpulse(CGVector(dx: 0, dy: 30))

into
bird.physicsBody?.applyImpulse(CGVector(dx: 0, dy: 22))

I tried different values and 22 was the most suitable one.

This GIF below is the original game

And this is modified version

Note that here the player touch screen more times and this makes him get into game and pay more attention to the bird's movement.
