"Your pet is now kind."
This is such a well executed take on the theme, using the same concept as so many other games in the jam only better in every area.
I didn't feel like I had to optimize my pet towards a goal or style, I felt free to pick whatever I imagined my pet to be like, especially with the brilliant personality/action questions. This really felt like evolution, gradual adaptation over time, compared to many other games where it's just a linear power progression with unlocks (like practically every game ever).
So when, after making a bunch of choices and focusing on eating carrots and apples, I get the confirmation: "Your pet is now kind." My heart got all warm. Such a great experience.
Did you make the art yourself? The level of quality is ridiculous for such a short period of time, so for your sake I really hope you didn't work that hard over the last 10 days :D
If I'm to suggest anything for a full release, it's to really focus on the "home" area. Make the pet move around and do stuff, and have the different actions you can do be implemented in the scenery instead of "popup panels". Implement more of the "tamagochi" things, I guess, so the player can stop what they're doing and enjoy watching their pet.
