Go to the ghost house level. Collect the light block and dont enter any doors. Keep going and examining everything until you come to the realization that there is a door in a blocked out space seemingly impossible to get to. Well the wall on the right side of the space where the door is a fake wall, you can walk through it. go in the door and complete the level from there.

in world 1 at the tower there is a red flag that you need to get to unlock the cannon.
you can unlock a level with a pipe and cannon around it (i got it on a red flag on world 2 number 4 ) and finish that on a cheat flag( the yellow pipe above the other 1). this will unlock the cannon.
