Improved Instructions

Edited the game description to both include a visual reference to augment the in-game instructions, and to indicate that the expanded lore in the description is just that, expanded lore, and perfectly skippable. Also updated the game to print the intro and victory screens one line at a time instead of all at once, and to disable "press any key to start a new game" until the whole screen has been printed, to eliminate the situation wherein someone would be playing the game, win the game while still in the middle of pressing keys to move around, skip the victory screen, and start a new game with no idea why they lost all their progress.
