Damn, this was a pretty hard game! I didn't think the gameplay was even that good. It just wasn't that well detailed. It's still okay for a puzzle game. I'm just not even into those. Thank you for including those hints.
Why would a hamster be a lab rat? Well, if I can't figure it out, how could a lab rat? I guess it was pretty unique. It probably needed some music. I just wouldn't recommend it.
