I wish I could post some bigger gifs, but this first picture is from my original mock up for the game, which kind of showcases the UI a bit. At it's core, it's just a point and click puzzle game where you explore the house. If you click on the character portrait on this screen, you would swap to the other character, who would be in a different location.
In the second and third pics here, this would be one of the first puzzles in the game, in which you would need to set the table in a certain way (how you're supposed to set it would be determined by the pictures on the back wall in the room) A lot of the puzzles would have their own screens you'd solve them in, so for this one, you'd just be choosing where to place each piece of silverware.
The last pic here just shows up what it would look like when a player would pick up an item.
