Maze Runner but The Walls Are Lava and You're Being Chased By a Big Ball

This is a game for a class at NYU Tandon. 

It's a simple rolling ball game that has the player control the ball. However, the player is being chased by a big black ball and has to escape from its  pursuer. Oh and the walls are lava too. The player has to escape by jumping into mirrors that lead to new dimensions. The game is in a first person perspective and the player has the ability to look behind them by pressing space bar. The enemy uses the built in AI Navmesh provided by Unity to follow the player. There are some bugs regarding the enemy clipping through walls and the camera rotation is also wonky and didn't match the behavior in the editor. These two things would be the first thing I'd like to fix.
