Kinda confused about what needs to be done for a while, but after reading the other comments seem like the idea is trying to spot if there is any anomalies and eat the corresponding fruit. The art looks pretty clean (looks a bit The Sims-inspired) and some music/sound would definitely help.
Also the navigation in the world is kinda odd, I was stuck on Day 1 for a while since keeps going out to the kitchen to eat the fruit, without realizing I have to click the bed to proceed to the next day (since nothing is different when clicking on the bed) thus looping the first day over and over. By the time I kinda figure it out it's getting pretty frustrating already so I did not proceed further.
