The art is absolutely adorable and drew me into this game! I loved being able to house all these critters and seeing them make the apartment come to life.
Theme: It fits with the theme of building connections between rooms, but I wish the connections did something more other than visually connect the rooms and to let you build deeper underground. Maybe some extra bonuses, like your habitants being able to visit each other.
Gameplay: Gameplay was engaging. I found myself filling out all 99 rooms. It felt like this underground apartment was bustling with life.
Art: The art is adorable. I can't say it enough. The music and sounds accompany the gameplay and fit well.
Overall, I had enough fun that my apartment had enough gold/stone income to able to build new luxury rooms every couple seconds. Solid and polished game, given that you only had a week! Good work!
