Really cute game. I liked the art style. I loved that there are side quests. I didn't buy the cat food at first (nor had I gone to the top floor) when I got the golden key. Before exiting the building I went up to the top, found the cat and I immediately went to go back to buy the food, I couldn't left them without it. What's the name of the cat?
Anyways, I've would love if this game was a bit more longer, I think the unused floors are a great real state to add more stuff (either for the main path or the side quests, both would be great). Nice job :D
