Quickplayer video of Exsperiment 2 UNITY

In this video it demonstrates how the terrian can be developed and experimented with. I made a house and landmass to make my unity work have the effect of looking like a real island that someone lives. I took away the main camera and replaced it with the first person controller, which you can see out of when you switch to game mode. This development was made through a youtube clip  https://www.youtube.com/watch?v=QUCEcAp3h28 , that I followed- but remixed to make my own- A i feel like if I totally want to understand UNITY software, I have to start from the beginning and learn step to step.
