I agree that the music at the start is overwhelming. I had a headache playtesting it! The water and food, as you said are probably draining at a high rate even when idling. One solution we thought of, was to not drain when the cat is idle, but we can never have enough balancing of values xD. Maybe the tutorial on the wall isn't the way to go, rather force it on screen and a UI popup to show the interactions. Thanks a lot for playing the game and providing this valuable review and feedback!
