Let me complain more about the interface. A standard panning display. The cursor also indicates action hotspots. Other action spots do nothing when you click on them. These, you are told, are places to use objects .
Problem is, the game is sometimes too complex for it.
The cursor change that indicates this is sufficiently unobvious that I didn't figure it out until after I'd finished the game. And the final puzzle, while a brilliantly clever piece of game design, just absolutely doesn't fit into the interface. I knew what I wanted to do, but I stumbled through doing it by pure trial and error. Hotspots appear and disappear at random. Navigation stops working.
