Was able to create a functional 'PlayerController' script that allows the player to walk, jump, grab, throw and wall jump. I rewrote the code to a get a better understanding of the functionality while also simplifying  it in the process. Grabbing still has a minor issue where the player has to jump on top of the grabbable object at times before they can actually pick up the object. I believe that this actually adds something to the gameplay but is overall unnecessary. I created scripts that allowed triggers to destroy objects and ones that trigger the next level. Currently I am very happy with the overall mechanics and am in the process of gray-boxing additional levels along with creating a script to move objects and a script that spawns objects. If I run into issues with time I would prefer to keep a more simplified art style rather than lowering the desired number of levels.
