Hi, finally got around to having a look at your game.
I'm afraid I didn't understand the instructions as I'm unable to read your language, but gave it a go anyway. I wasn't sure how to interact with things but I did have a look around. Movement is pretty smooth but I did get stuck on objects from time to time. I got the impression that the cats you were supposed to serve waited at their tables with trays ready to receive food and that you are supposed to give them food and get money in return that you then need to spend on more food at the shops nearby.
It seemed like some things could do with a bit of improvement and as much as I would like it to all be in English so I can understand the description on the game page and how to play, I don't think it's fair to expect everyone to make their games in English if that's not their own language just so I can play them, so thank you.
