Ah, forum back in shape... what I meant to say, but couldn't, was this:
Another great game from you!
I also have a small suggestion... what if the green lines got gray again if you went on them twice, but only if you don't already have the entire square. Could help improve gameplay by changing it from "RUN" to "RUN, but know where to turn"... On the other hand, maybe you just want run, and I'm guessing that's what the original was... just an idea, though. Of course it wouldn't work if it was that way for all lines, you'd have to think too much, but as long as the lines surrounding a square already "checked" were safe, it should work... I don't know
(Also sent this to your mail, kev, because the forum was behaving strangely at the time)
