Well, I couldn't pick things up I wanted to pick up or put down things I wanted to put down. I could shunt objects into place, which seemed to work but probably wasn't what I was meant to do. I couldn't change the background screen - was it indeed changeable? I never figured out what the pads marked left and right were supposed to do or how to use them. OK, so there was just me playing, so I knew I was going to have a hard time, and I realise that a lot of the charm of the game comes from blundering about in a room full of odd items, but in the end I found it frustrating that I knew what I wanted to do but I couldn't do it. People with better user skills than me will probably have a much better experience!
