Just finished this and I’m still grinning like a loon. I started playing thinking it would just be a fairly bland process of just working my way through all the test chambers until I got cake, but my god, it’s so much more than that. I don’t want to give anything away, but needless to say, I fucking loved it, and the humour in is top notch. I only have good things to say here.
I read somewhere this was a laugh, could well have been this thread looking at post dates so i’m downloading Portal:First Slice which i’ve just seen is a demo/first few levels.
