Mediocre
While the gameplay was direct and to the point, there was no back story, and for the first time I played, I didn't know what the objective was until I saw the "Author's Comments" and the title.
There was not as much as a title screen, and neither was there a help section, the only clue I could move using the mouse was that the character moved when I moved the mouse.
5/10, a 2/5 from me.
