...this app would do the trick, i imagine. it's extremely basic ("primitive" might be a better word - it reminds me of the most primitive games i ever ran on my Mac II back when that computer was the pinnacle of Apple's technological achievement...it has the retro look, feel, and sound of a beginning coding project released into the wild by a hobbyist)...you just traverse the increasingly complex mazes to get to the goal(s). and since finding the path from the start to the goal is really the whole point, once you've done that (which you do before you actually traverse the path) there really isn't any reason to actually traverse the path, except to make the game present you with the next path.
i think one of the two previous reviewer's commended this app on it's clear sound; if that's the case, that reviewer doesn't hear very well. heck, *I* don't hear very well and I can tell the sound is anything but clear. 😄
