Quote:How do you figure?
If you want something to be invisible then it shouldn't appear when it is touched. Appearing wall mazes can be turned into blue wall mazes, which I think are much better because you can see it coming and you know where you have and haven't been. Invisible walls can be used to make some great levels that would not have been as effective if other tiles had been used. (For example: STRIPES? and VANISHING ACT)
