When you die in space there is no sound, not even that little 'ehhhhhh'. Mr. Kaufmann, a University of Michigan grad student along with help from fellow grad students (whose majors we suspect were math with an emphasis on physics) put this complex, challenging and nerve wracking scenario together. Three levels and . . . you're a Doctor! Level one moves slowly until you figure it out, pattern buffer is available on into the scene. Very articulate terms with words like helix and advice like "remember your Newtonian Physics". huh? Level two is where that 'what goes up must come down' comes into play. This level, oh my Aunt Fannie, good luck! Still, we were jazzed by this Map and looked forward to the end, however when you make it to level three, read the term, and follow directions, you crash. At least we did. Several times. That dead halt while trying to make a move. Tried to no avail, must be a nasty bug. BUT download and play 'til you crash 'cause this is almost a winner. Challenge with a capital "C".
