Thank you so much for the kind words and great ideas ^^
Kitties lose happiness when you ignore their needs, and the less happy they are, the less kittycoins they give you. I’m working on a system where kitties request certain items and reward you for giving it to them, and their requests will be based on their current needs. I think there should be more feedback for when kitties have unmet needs though, you’re definitely right.
Tabletops are coming in the next update! It was pretty hard to implement since I kinda programmed the 3rd dimension from scratch (I do not recommend) but I’m really happy with how it’s turning out, though it’s a little janky and might take some time to polish. The next update will have a handful of tables though that you can place items on, and physics objects will interact with them like you’d expect.
I considered a day/night cycle, as well as weather. It’s probably something I’ll implement, but I’ll be careful when I do so, since personally I get a lot of eyestrain from colorful games cycling between bright and dark (the Terraria title screen/character creation is just the worst for me >w< )
I like a lot of your little ideas around these concepts and I’ll definitely read back on this as I continue working on the game ^^ I appreciate it!
