Woah, this was only made in a certain number of days? I can't believe it! I have no clue why this hasn't already won Daily Feature. Then again, I don't really think that's how the award system works here. It was a bit difficult to tell if the main character was male or not. It's funny, because I was thinking the exact same thing about being able to time travel forward in time.
Now backwards time travel, that's another ball park. I love the quaintness of this. It seems like you may have been trying to imitate Miyazaki. I guess all really good anime-esque work can be compared to him. The ending was a bit sad.
