There's always a lot of cutting corners going on, and I actually like the approach of showing animations, keeping the technicalities hidden from the player (like real foxes). I think mine have died from hunger 😅, but now I know I shouldn't be petting during daytime...
Oh, one last remark, I thought there was a bit of a disconnect between "the neighbours are playing bad music" and giving the toy to the fox, I deduced from the context it's what I should do, as the other cause and cures are pretty logical, but this one actually had me petting instead of giving the toy.
I just thought (but I don't think you guys will rework the spaghetti to make this possible) what could make this game's shop loop more engaging is to have actual upgrades. A litter box where the turds could go, for example, or increasing food quality by buying a better kitchen or so... Would make it more strategic instead of purely reactionary, if that makes sense.
Anyway, looking forward to the next game you'll make!
