Also recognize we're being a little more nitpicky because
1) you asked us to
2) we've seen similar mistakes or issues with maps before
3) with limited terrain it requires even more care in the design. when you have "too much" terrain it's a little easier to fudge some stuff or get away with others, but slim terrain really requires a certain finesse to map building. We're trying to help that finesse.
4) the more I play heroscape the more I realize it's a Chess game. While dice are involved, games of heroscape are won and lost by 1 single hex. The more competitive a person plays, the more meticulous they study a map and it's subtle advantages and disadvantages and they will be able to exploit any potential mishaps by the designer. We're trying to help designers be mindful of some of those things. So take courage, you're doing well...but after all, this was meant to be a challenge...and well, it is a contest too.
