I don't really understand. I bought a ton of what I'm assuming is food and waterbowls, and seemed to have sold some Rabbits after fiddling about clicking on random buttons for a while. Some customers seemed happy, some didn't, but still payed me a lot of Money. Ran out of Bunnies after a while.
Some pieces of Food or Water or whatever had small blinking numbers(?) next to them. Couldn't figure out what they mean. In general, couldn't figure out what anything means, I don't speak whatever Language that is.
Sorry.
