Its simply a pet that runs/sleeps on your screen. I had planned to add more features/interactions, but i had to take a break from development over the summer as some personal stuff had come up. I do plan to continue it in the future, but I have another game I'm focusing development on.
Edit: I am wanting to add customization/custom pets in the future, I saw your looking at ducks and I could potentially add one as a option next, if your still interested.
