Meme Simulator (FlyingTurtle)

This is a game where you control a cube that has to dodge obstacles to get to the end of a level. The game is called Meme Simulator because I changed a bunch of textures to memes. I made the game with this tutorial by Brackeys. 

Controls: Use 'A' to move left and 'B' to move right.

The ground is not supposed to fade to the colour of the sky so if you know why it is happening could you please tell me in a comment below. It does not happen when I run it as an exe on my PC or in Unity.

The "Quit" button at the end is a remnant from when it was an exe. It does nothing.
