How do you unlock the cannon on World 1?
Games Guru: Great game! So, head over to the tower. Make sure to have the Blue Shell with you. Head into the first pipe that’ll shoot you up. When you start falling back, go in the gold door. Don’t be discouraged by the many moving platforms. See the one on the right near a gap that always stays the same size? Walk into it and notice three blocks. The Blue Shell will break them all. Keep breaking! Move right and finish the level to unlock your fancy Warp Cannon. It’ll take you to World 5!
Are there any other unlockable characters besides Luigi? On the touchscreen in my instruction booklet, it shows the worlds but on the actual touchscreen the worlds look different. Why is this?
Games Guru: Unfortunately, Luigi is the only unlockable character in the game. Regarding the difference between the booklet and the actual touchscreen worlds, sometimes the people who make the booklet get an earlier version of the game design document. They should have gotten one that looks like the real thing. But sometimes when deadlines are tight, some things fall through the cracks.
Are there any cheats or hidden characters?
Games Guru: I have not tried this myself, but as I understand it, if you press and hold the L and R shoulder buttons down and choose one of your saved game files on the select file screen, you can play as Luigi.
