sorry this reply is so late, thanks so much! Level eight (and actually level six) is a very gimmicky level. You either get it or you don't, but at least with level six there is a mental process to solving the puzzle where level eight only has one step to understanding how to beat it. If i made the game again, i would probably reuse the gimmick in level six to make a completely new level, thus making the mechanic learned in level six more useful and getting rid of that awful one-dimensional level.
