Thats the last cafeteria stage right? I think that is the hardest level, after it I introduced different kind of enemies as well since it was impossible to do anything with more/faster enemies, I already nerfed that one :D Your aim should be isolating the yellow, or maybe a yellow with another. I am gonna do some other test runs later today, and maybe nerf it a bit by making them a bit slower If I can't beat it. I must admit I only beat this one once, but I was also pretty tired playing levels for hours. I was so happy I made it it was "passed" - but rest assured, the next ones are not that hard, and also you will need some tactics for some levels. Oh, and that was the reason I came up with the "Hard Level" warning, it pissed me off so many times :D
