I think these maze idea has real potential, but the one thing I get hung up on is that you don't have to go near most of the level, so once you develop a route that works well, it's no longer really effective as a maze. If there were more flags placed around the level that would require you to back track a bit to catch an updraft in order to get to a higher level to chase down a flag, then that would add some spice to these
You want Mission #20 in the Hall of Fame? It is hard, but it could work. I wasn't sure if anyone else would want such a long level in the Hall of Fame.
