Awesomeness.
Very very good, I don't have to explain why, it's excellent, especially for a demo, and I hope you make it even better and release the final version here. So, with that established, I just want to offer a few suggestions for the final version. The file needs compression, it's very big, see if you can do anything to cut down the size. The characters move kinda slow and the response seems a bit slow, too. And finally, check your grammar or ask someone to proof-read it, there are a few glaring mistakes (such as the word "aftering," which is actually not a word). Just read it over again and have someone read it to weed out any mistakes, that helps a lot with any written work. Good luck, keep up the good work.
