Far better than I expected!
When the knife came out, I thought that that this was going to be just another violence-fest, but it was really, really imaginative and nicely done.
I loved the various endings and by the time the credits rolled, I was definitely unnerved.
Graphics and animation were nice, but the sound was awesome.
Also, I loved the tiny messages, specially the warning about being a nosy person. :)
The extra didn't seem that great to me, but then, it was just an extra.
It might have been nice to have the explanation stay and be selectable at the end, and also to have scene selection at the end...
I'll have to come back to see more of your stuff sometime. :D
Keep up the great work,
Bez
