Well, it turns out that one week isn't long enough for me to finish a game by myself when I have to work four days of that week. Much of the gameplay is unfinished, but I've uploaded what I have to give an idea of it would have been like. There are no pegs pre-placed to tie strings between as there should be, but in this development version, pegs can be created arbitrarily by right-clicking. Ultimately, there would be a limited number of strings of different types and lengths available in the bottom toolbar, but that also hasn't been implemented yet.
