"2D Dimensions" Mini Platformer

This is broken project that I was ambitious about. I begin working on it 2 months ago but I ran into so many technical problems and bugs, mostly due to my limited knowledge of the Unity Engine and C# Scripting.  With that being said, I will use this buggy, broken prototype as a learning framework in order to understand what went wrong and what I can do to improve my knowledge of game development with Unity 3D. 

Assets used are:
