+ </h2>
+ <p>
+ The <var>roadLength</var> game input variable used to be the
+ cardinal number of positions the troll could be in. That's the
+ way it was presented in the original game, but I leaned more
+ towards distances to make the I/O protocol easier on beginners.
+ So it's currently inconsistent.
+ </p>
+ <p>
+ This is going to change in the following days to be a distance
+ everywhere, more in line with the protocol's other measures.
+ Not to mention being somewhat more consistent with the variable
+ name. Thanks

+ for reminding me of this.

+ <p>
+ If you used this variable, I suggest you temporarily used one
+ of these workarounds so you don't get bit by the upcoming
+ change:
