Thanks! L-Sync suggested to use a play carpet to illustrate a child’s room, and then I had the idea to make it look like the main character was standing on some sort of overworld (as in classic RPG where it’s okay to have a giant character compared to the rest of the map).
Initially, the character was supposed to be able to walk on the houses (which would be part of the carpet, so flat), and then it would say “?”, as a kind of fourth wall joke as the character would obviously see they are flat, and the optical illusion would only make sense from the player’s point of view, trompe l’oeil style.
But eventually we added colliders to the houses to make them stand like real toy houses, as I had plans to let the bugs use them to live and store stuff.
