Walking Blocks

Hello, This is my first game that I believe I did an alright job on so I hope you enjoy.

Keep in mind, I'm not very good at making games so it may not be very good.

Instructions for game: 

In this game you will see a grey square, a red square and a blue square. Your objective is to get the grey square onto the blue square using the 'WSAD' keys to progress to the next level. When you move, the a red square may move toward you. If a red square covers you, you will lose so make sure he doesn't get to close. 

As you progress through levels, more red blocks may appear.

Each level after the first is randomly generated, making the game endless (if you don't die of course).

Thankyou
