This doesn't seem to work at all for me, but I don't see any error messages in the console or anything... I just see a dark gray screen with an (i) on the top left (with the instructions), but nothing seems to have any effect (left or right clicking, using the scroll wheel or dragging the mouse with left or right click) don't seem to have any effect. The only effect I'm seeing is right clicking on the page shows a "[CLIENT TRIGGER] Right-click at (123.456, 789.012)" message in the console log.

I can see that there's some traffic (for example, I see some WSS on socket.io, and some XHR for /state, /clients, /checksum) but it doesn't seem to change anything on the screen.

looks like people somehow deleted everything, reset it to starting position
