This is really good for a free VN. It had one of the tensest moments I've experienced in a non-strictly horror game ever. Very glad I played this 4 years after its debut because waiting might have killed me. Some of the ending stuff felt a bit rushed but it was still good.
i think the game would be much improved if, at the end, the camera panned dramatically to reveal the return address on the box addressed "from T. Kaczynski"
