When it said one room, my expectations weren't high; they were surpassed in spades. I loved almost everything about this. The descriptions were great with some subtle humour thrown in, without being tiringly verbose. Most things gave a response, and generally a very good one, (though there were a few situations where half a dozen things are mentioned and weren't understood - could easily be tightened up, but didn't detract).
The problems aren't challenging and normally that would put me off but the unusual nature of this game and the beautiful, well paced unfolding of the narrative was compelling so that, as with all well-crafted fiction, I couldn't put it down.
I would reccommend spending a pleasant hour or two with an ice-cold beer/water, feet up on the sofa, music/radio playing gently in the background and lose yourself in this great little adventure!
I certainly did.
