The sheep tend to stay by the edge of the screen so I couldn't see if they were infected or not, or what they needed. Also, the sheep reproduction seemed random- needed a SFX or something to indicate there was a new sheep. Also, some indicator that you are running low on food, that killed me the first time and I was so confused what happened. Also, another timer indicator on when it is about to be night or day and some transition between them might be nice!
Really cool game! I really like it and would love to see more!
