I think some improvement can be made to the visual hierarchy and contrast between the background - simple things such as a stronger dimming filter during the tea mini-game. It took me a second to notice the right side of the table because all the colours blended together. Another thing would be the trash placement in the house as most of them were covering the bottom navigation bar.
There was a lot of content to enjoy and I was surprised how quickly things changed in the household. I loved how the music changed depending on which task Roby was busy with (also the bgm variation later on). The game also does a great job at making the player feel helpless as a little cleaning robot watching everything unfold. Enjoyable and well made :)
