Remember slide puzzles? Those little squares of plastic covered with yet more squares that had to be shifted about to create an image? I think of them with a cold shiver of dread and a sense of frustration past. Imagine my horror when I realised that the whole concept behind Rooms: the Main Building was centred on these tiles of hell. While it’s not quite as bad as I feared, 100 slide puzzles with a few nifty effects does not a brilliant game make.
