This is a cute and simple game. I like the art. The layout is pretty good for giving space to move around, while not being too big. The music works for the game. This was fun and after I learned how it worked I retried for a better outcome with more animals surviving.
The instructions say to click on a suspicious animal to send it to the lab, but does not make it clear that doing so ends the day. It should really be more clear that you can only send 1 animal to the lab per day, so that on the first day you know to spend more time making sure you pick the right one. It would also be nice if it told you in advance when the day will end if you do not send an animal to the lab before then.
