An old project that I recently picked up and finished. Update 3/11/2018 - Only minutes after the project was shared, I reversed the color roles. You now play as X and the CPU is O. Update 3/12/2018 - Added a start screen and the option for the computer to play first. Update 3/14/2018 - Added 2-player Update 3/15/2018 - fixed the glitch where every mode is 2-player.
