The UI design might need some work.

It starts with no controls, just a picture. I hit esc. Things start moving. It keeps moving, I keep hitting esc, it doesn't stop. I try ctrl-c , no dice. I look around the frame for buttons. I try one of the buttons, it moves faster. I hold down esc. It doesn't respond to holding down esc either . I see no way to gain control. At no point do I gain control.

Ultimately it stops. Fine. Ok, no response to WASD. No response to drag motion. I click "Instruments" , I get a side-bar "instruments of the museum" with no contents. I click in the side bar. Now I can't close it, and other controls are gone. I try hitting esc. Multiple random clicks later i'm back where I started.

I try the "more" button", I am now looking at a painting sideways, and an anodyne text which explains very little. I click on a painting. Things start moving. I hit Esc. Suddenly the painting is full screen. GREAT. Ok, and now how do I get out? Esc? Oh esc. Ok NOW ESC... oh no, things are moving again. I didn't mean for things to move. Esc shouldn't cause things to START moving. hit esc again. The esc is ignored.

I end up at another painting. I try some buttons. Most don't work. I hit esc again. Things start moving. I didn't mean to move away from the painting, I just had it in front of me!

I am very confused.

I'm not in control here.

edit: "Esc shouldn't cause things to START moving"

Thank you for the detailed feedback. You are right, there should be a way to stop the walk while it moves. We will add that. ESC to close is however intended. The Instruments panel closes with the button at its bottom, but more intuitive would be at the top and we will move it there. The walk is guided on purpose, so WASD and dragging don’t work, but we should say that.
