I got up to the white books shelf but wasn't sure if I completed the game? also there is some cheese possibilities by spamming space ^_^ Not sure I see the connection to scale? Very nice game, would have loves to see more polish on the art, for example character walk cycle (you can get it for free in Mixamo for example) or more toys to make the shelves look more realistic and feel like an actual toy shelf.
Overall nice game concept!
