You've got a working game. You've got a character running around. OK, so that was cool while it lasted, but now you want to see more and do more. You've come to the right place because this is your first "Quest". Yes, quest. You're now on a quest. I suggest that you find a good chalice and a horse or, at the least, a very capable pony.
In this first quest, appropriately named "Quest 1," we will be taking our snazzy little back and forth walking game and giving it some pizzazz.
