use each player's power strengths wisely
I've been playing this game for a couple of days now...47 on the ww leaderboards with 40 gamerpoints. I have all but turbot checkpointed to 20...I find that I get farther with Vector or Vixx. You can activate his power when your screen is almost full and get by. I try not to wait until the last second to activate Sprocket and Turbot as their powers auto targets the bricks. To get the puzzle commando achievement, get as far as you can with a character and familiarize yourself with the puzzles. Then start from the beginning and try to solve them on this pass (or the next...etc). Good luck!
