Single Prefab Dungeon Generator

For a challenge I decided to see if I could create a game that uses just one prefab within its level construction.

This is the result of that challenge. This single prefab generates the level, with a little bit of detection to remove walls when the cross over with each other.

R will reload and regenerate the dungeon. The game does generate a randomly positioned exit point as well. Use first person controls to try and find it.
