Good idea, and great implementation of the scale model of the room. There are a quite a few submissions playing around with the idea of a large and small version of the same room, and this is a pretty well executed one, for sure.
I think if the scale model starts off in a diagonal view, such that the 3 circles used to control the axis rotations all seem to be different shapes on the screen, it would be easier to rotate the model correctly. Also, lighting could be a bit better.
Overall, a fun game!
