I've gotten a lot done this weekend, and will continue working on this for some more hours. Basically the idea is that you are a blacksmith, and you must make and sell swords for the people who want to buy swords, so you can buy stuff that you can use to make more swords. At the same time, there are skeletons coming from the other side who want to kill you and/or destroy your stuff, so you have to "sacrifice" your swords by throwing them at the skeletons. This makes it kinda a strategy game, as you have to plan quickly, what you are going to buy with the money you get from slaying skeletons, and selling swords.
