When you move the chair with jack, you can do it from the right side of the chair which makes the chair move on top of you.
Fortunately you can still move but it should either not be possible to move it from the right side or take into account which
side the player took when they interacted with the chair.

There's a spelling mistake when you reunite with Jack "Your right" instead of "You're right."

Since you're allowed to walk on dolls, the dolls that are behind grids allow you to walk on them and go through the bars.
