Yeah, I think I've tried almost every possible permutation, nothing gets me very far. I'm fairly certain the 100 level one is also impossible, the 100th level is your basic brawler rush.
I played a little more and like it a little more now :)
The reason I find it a little boring its because you waste most of the time wacthing the guys pass trhu the maze and thats not fun since the graphics are not amazing. Despite that its fun.
And anyone else noticed that the game uses sounds from lemmings? I would reconize that escape yell anywhere :)
