A well done adventure!
I have never been fond of "clock" movies. All those CG voices and simple animation tend to get old fast.
However, this game was pretty good. It actually wasn't very complex due to the ending and limited branching dialog. None the less, I really liked it. It's nice to see something a little different like this once in a while.
The artistic style was pretty good, if a little short on contrast. I also enjoyed the two very fitting pieces of piano music.
I would guess the file size could be dropped considerably by removing the voice overs. I know they are standard fare for clocks, but they aren't really needed THAT much. A little "continue" button next to the text would have been a handy addition.
Anyhow, keep up the good work. I look forward to more!
