Basic Raycaster 2D

This is a 2D raycaster that will be leading to a larger game I plan on making. 

"In simple terms, a raycaster is a 2D renderer that fakes a first person 3D perspective by casting a set of rays (lines) for each x coordinate of the display from the camera to the nearest wall in front of the camera. Walls are drawn in vertical stripes and the height of each stripe is determined by the distance from the camera." -Github

The larger game I'm making for this will be a different upload on Itch.

Controls:

W or Up = Forward

A = Left Strafe

S or Down = Backward

D = Right Strafe

Right = Turn Right

Left = Turn Left

I do plan on using mouse to turn the camera, but as of right now it's the arrow keys. 

A 2D Raycaster is like Wolfenstein 3D is possibly the most popular Raycaster out there, it's a 2-dimensional game that has more 3D aspects. I'm not good at explaining it, so just go ahead and search the internet for better demonstrations.
