What a disappointment!
Maybe it's me, but I couldn't find any instructions. Lots of info on types of terrain; none on how to find the start and how to move the robot (which I couldn't find either). Also the mazes are way too big for the screen (mine's a 19-inch) and the little map overview is too smal and doesn't let you trace your steps on it.
You need to be able to see the whole maze in order to make choices about where to go.
I would like this game to be good, because I love mazes, but as it is, if it were free, it wouldn't be good enough.
