After a week or more off it (Oblivion and stuff sucked my time away), I’m back on it, getting coins and unlocking routes. I’m pretty sure i’ve unlocked all the actuall levels now, but not all the warp cannons and houses.
Anyway, today I finished off all the coins in World 3, and found the Warp Cannon to World 6 in the World 3 ghost house. Once in World 6 I set about finding some more coins, and managed two more levels-worth.
How in the hell did you find the warp cannon?!? I can’t find it- can you tell me the specific location of the warp cannon? You can email me at leolxu@yahoo.com.
