I loved the art and the music, it really gives a cozy yet energetic vibe to the game. Art for computer screen is really cool too. I also liked the irony and funniness of these cute pets being hackers.
I think game lacks some tutorials though, it took me couple game overs after i realized what consumable items do for different pets. But after realising if was fun to guess what each pet likes or dislikes. I think it would also be better to have some kind of pop up when an item is used like when you give food to a pet it should show how much fullness it gives or how much happiness decreases when you use a training data.
So overall i think game needs a little more communication with the player. Besides that game feels very polished and it's clear how much effort was put. Great work!
