The Textfire Demo 12-pack was released on April Fool's in 1998, claiming to be demos of an upcoming commercial studio called Textfire.
This is one of the weaker textfire games. There is a machine that turns you into an inanimate object (including one inappropriate one, an option that I never ran into).
In this 'demo', you only get to be grain. You can't do anything. This was done much better by the game Constraints.
