After I got too close to this test, I took a break from this. And finally, I finished to revise. It was great to put up this on ACME online, and all the feedbacks from Proswere very helpful. I also got feedbacks from Justin and Mike, and it was very helpful, too. I realized the ending was not clear enough, and I've should re-do some keys. So I finished. And there are still many things that should be improved, but for now, I decided to move on to next test!
