GOD I would have love some "shlop shlop" and some "munch munch" and even some "woof woof"!
Very addictive game, I got to like 2500 gold before forcing myself to quit. The animations are super simple but work perfectly. It was also fun to manage the dogs patience and hunger. Good job!
I think depleading food and making the player pay to refill it would have been a good addition, that way the types of food in each spot could change as the game progresses. Once I all plates full of food the game progression and difficulty platoed. Another thing I would add is an ending. Like at 1000 $ you get a cool animation of all the dogs happy and the game ends!
The game is awesome for a solo dev. Good job!
