For this update, which is significantly smaller than the previous, I've made the addition of two much harder levels to go with the eighteen from before to make up an even 20 playable (and beatable!) levels. Also, I've made a huge edit to the opening dialogue, making it much more explicit as to what the storyline is about. I think this is as far as I will go with the storyline and main-screen from here on out, unless there is something brilliant that comes to mind or is suggested. Below are two screenshots: one of the opening dialogue, and the second of the 20th level.
