Unity Day 1

Today I started learning Unity.
I started with a tutorial about the basics from:

Game Maker's Toolkit

The first game I'm going to make is Flappy Bird.
A simple game but good to master the basics.

This is the progress of my first day:

• I downloaded a sprite from the Unity Assets Store and used this
  as the main character.

• I wrote and added a script so that the bird can move up and
  down.

• I added the tubes to spawn on the right side, and using a script
  so the tubes move to the left. So it seems that the bird is
  flying.

• I made a scoring system and a GameOver Screen.

• Later I wrote a GameOver script, if you touch the tubes you get
  the option to start over.

• The script for the score system is added to the trigger between
  the pipes (picture 3)
