The concept is hilarious and fits well with the theme. Who doesn't love cute hamsters? I just have to try not to think too hard about their family tree. I did have a couple of issues with my hamsters staying suspended in midair after I set them down, or even floating off screen in some cases, but that wasn't a huge deal since they always ended up back in the cage. The hamster "facts" on the loading screens are fun, as are some of the hamster names.
