Generic Cube Game (jimmelton)

This is my debut into the world of game development. I am relatively new to both gamedev and programming(especially in C#), yet I am proud of myself for actually completing the game. Whenever you collide or fall off of the map, it takes 4 seconds for the game to restart. I also plan to perhaps update this game in the future, giving it somewhat of a story or further gameplay elements. Any constructive criticism is encouraged(seeing as its my first game lol) and I would greatly appreciate it!
