Cute.
Cute little flash, I really liked the opening animation with the wind blowing across the grass and the little hamster scampering along the tree. It felt very calm and peaceful. Although, from what you said this was submitted as part of a project for physics. While, i really don't like most school projects that are submitted (Mostly because they aren't really that good, with the exception for Final Fantasy A+ Which is FANTASTIC by the way), I found this to be cute and entertaining. While, the animation isn't awesome, I did find it had its own little charm.
Not a bad flash, but not incredibly good either, I would like to see another Flash from you though, as I personally feel you do have the skills to make some really good ones!
