So far really like everything. A few small nitpicks would be things like the ui for navigating the house feels a bit bland for how good this games animations and character art are. Having it be awkwardly off to the right feels a bit weird. I think having a labeled mini map i think would be more aesthetically pleasing.
Second thing would be the sound design for the expansions themselves. I'd use sounds that better emphasize the inflation effect, like tense stretching sounds and the final pop having more "boing" to it.
Other than that I really like everything else. the phone ui is good, like i said before the art is great, i like the voice acting, the concept is fun and the minigames and their respective animations are really fun.
