Love, love, love this little game so much. It's so informative and educational, while also having so many wonderful babies!!! One little gripe though, and this is 100% ONLY ME saying this. But could there possibly be an option in the future to turn off death and getting rid of the euthanize button? I know it's realistic in the life stage sense, yeah, but one of my goals is trying to get the exact coat of the ten rats I've had in my life. I've already lost all my babies once and losing them a second time, even virtually, makes my belly hurt.

I ended up playing this for a couple hours when I first bought it. Graphics and UI are super cute. I managed to get a champagne colour rat early in, so I was determined to breed more of them! I can't wait to see what else the developer has planned for this game.
