Infinite Maze

I don't know what's causing the visual glitches. and if you've got any ideas please write them in the comments.

I was thinking it would be cool to generate mazes, so I found a youtube video that talked about Eller's aglorithm (http://www.neocomputer.org/projects/eller.html). So I spent a day making this (all code is original, I didn't follow any tutorials). This was just a fun little side project, and I don't have any plans to expand on it for now.

I should note that while I'm using Eller's algorithm, my project somewhat breaks it by using chunks of mazes that I throw together and hope don't end up creating locked off sections.
