Nice.
Very good work. The art you used is well drawn, and your animation is very smooth. My only suggestion to you, is to make more possibilities. Once you've gone through every 'ending', there's nothing else to do except repeat everything over again, or see your favorite ones again. It's not terrible, at all. It just needs to be longer.
Keep up the great work, I'm sure you can easily improve this, I look forward to seeing future animations / games / gadgets and whatnot from you.
