Hello! Very cute game so far! My suggestions would be:
- Animation for working cats so it's more clear that they're doing something
- Status bars such as motivation, hunger, fatigue etc. Is a cat's motivation is high, maybe it makes money twice as fast. If low, it'll be slower or maybe even refuse to work at all until it's fed or has playtime, stuff like that.
- Not sure if coffee already does this as I haven't gotten the coffee yet, but maybe it could give a burst of motivation for a few seconds, followed by a crash where the cat is slower to make money for another few seconds before going back to normal. Perhaps one of the upgrades for the cats would be a better caffeine tolerance with longer burst of energy and shorter crashes.
- Making it possible to deselect a cat. The white frame always seems to be on one of the cats at all times and I keep accidentally moving the cats away from the computer when clicking around or placing decorations.
Keep up the good work and good luck with the game!
