Thanks for giving it a go and the feedback
The steps to open a door out of the big room:
1. pickup the stone disk on the table in the small back room
2. Interact with the dial on the pedestal in the middle of the big room which will place the disk onto the dial
3. move the mouse crosshair over the placed stone disk so the rotate icon appears and click to rotate it
4. Move the mouse over the center dial button so the use icon appears and click to press it
the dial works like a combination lock. Turning the disk selects the symbol and pressing the button submits it.
It’s my fault with the interface. I realized after the submission deadline that I hadn’t set up the interaction UI correctly to make it clear there are 2 actions at the dial that depend on where the crosshair is pointing. I’ll probably try to fix this after the jam
