v0.5 Release

Originally, a multiplayer version of this game was in the works.  However, due to UNet being removed in the near future and other network complications, multiplayer is being postponed.

Instead, we have a few additional game options.  There are:

-friendly allies (AI)

-adjusting the number of allies, enemies, and notes

-can respawn infinite times after "death"

A revive mode option will be added in the near future.  I am hoping to improve the ally AI.
