Thank you for the feedback! I guess I should've specified in my submission that I'm a level/environment designer and the intention is for this to be more of a block out of a level rather than a demo of a game. I'll probably just switch back to using a counter and take out the camera feature for that reason. I ran out of time and couldn't finish that feature, which is where a lot of the problems are originating. Turning it into a camera simulator is a great idea and I'll take that into account if I decide to make this into a proper game.
The doubling and sphere are a part of the skybox and I did have major issues with it, couldn't for the life of me figure out how to fix it. There was supposed to be an effect of a mountain range in the distance but it clearly didn't work. I'm seeing that the better option would be to expand the terrain and sculpt the mountains myself, that would also help with the boundary issue. There are still a lot of ways I can work on the terrain to box in the player, that'll probably be my next step along with fixing the more level and environmental problems. Thanks again!
