P6: Interactive Game • Implementation of a basic puzzle/rpg (Role Playing Game) /board type game with user interactivity. • Use of at least a basic level of heuristic in the difficulty of the game • Multiple outcome scenarios, with user choices being crucial at least at 3 points. (Tic Tac Toe has a minimum of 3 crucial decisions.) • Ability to save/load game states. • Challenge: rudimentary graphics display, using either ASCII character set or other such methods.
