I finished it. I played it ALL TO THE END and it is UTTERLY TERRIBLE.
It really is.
The characters with American accents are the ones who use the English colloquialisms "gimp", "git" and "sod". They sound really out of place since the actors clearly don't know what the words mean, and they pronounce them in such a funny way that it really makes it sound uncongruous, and nobody has ever used these words outside of 1990.
And the game is DULL. Let me tell you how dull it is. Imagine sitting staring at a blank wall. No colour, no texture, no smell, nothing. AND THEN IMAGINE DOING IT FOR 14 HOURS, whilst you know that everyone in the next room is having lots of sex with hot girls.
