very creative mini-games! My favourite was the one you needed to balance on the pole. I also liked the bubbles one.
However, after a while, I just defaulted at spamming things. The training gave the cat points regardless if I trained the skill it advertised it would train, and then I managed to keep playing with 0 and 0 in hunger and happiness. This included the grid game, it didn't really seem meaningful whatever I did.
That being said, its a completely different point than what you made here, which is an amazing feat! I guess "balancing" is what I am commenting on :D I guess the level of amazingness you have created, made me wishing for more meaningful choices.
