the laser are effed, they expand then fire. You have no way of know exactly when they hurt you, so collecting them is absurd. Add that with confusing, overlapping beats and level 6 becomes one of the hardest in the game.
Awful game. I'm not saying this because I'm mad at it. For one: Its lazer not laser! two: The lazers were a horrible design decision! "Oh, how about we make them bigger and turn on out of nowhere!?"
