Escape the Machine

A blue LED light doesn't want to be a part of a death machine, so he is using all of his rectangular shaped movement to get out of there, but the only way to do it is by going through the machine he want to get away from. 

Help out this small stood out LED light to get out of it safe and sound.

Use WASD keys to move this little blue rectangular.

Here is a GitHub link to my source code. If you don't have a strong stomach, i don't recommend that you look at this mess of a code.
