Too long to be fun and a lot of intricate cuts sprinkled into the first half of the level. I would be surprised if this wasn't optimal now. This is definitely Pathology's hardest "Long hole level" and a serious contender for hardest level in the game.
This level can make you somehow angry, if you're 2 short. :)) The second time around I hoped deeply, it won't happen again. And it didn't. :)
Such levels teach us to be carefull.
