You will be in immediate danger at the beginning of this level. Demonheads will spawn from the left/right mirrors, and head towards the opposite side. Yeah, you're in the middle.
Stay in the center, jump the pair of demonheads as they cross. As you land, run left.
Drop to the level below (not the floor), break a few blocks to your right, and step out of harms way.
Create a trap by extending the platform you're standing on all the way to the left wall. This will take a few trips back and forth.
Break the block directly under the left spawn mirror so that both sets of demonheads now fall into the trap.
Clean up the goodies, climb up the right side, exit.
This board will require precise timing and patience.
Get key by breaking the lone brick on the left
Make your way up to first level of gray bricks
Manipulate the timing of the middle pair of ghosts by spawning bricks. They should cross each other's path exactly under the gray bottle. You can time the ghosts by placing one block (in the path of the ghosts), under the fairy bell and then one directly to the right of it.
Do not disrupt the timing once established; use your jumping ability as the only way to avoid ghosts.
Make your way under the grey bottle by paving the way with bricks. At the instant you arrive under the grey bottle:
destroy the brick that got you there so the pursuing demon falls into the gap;
jump into the air so the middle pair of ghosts passes through harmlessly
Make your way to the right side of the screen for the final ascent.
Avoid the demons and make your way to the exit door.
Another option is to build blocks below each of the rightmost three holes before following the above instructions. This makes it a little easier because you won't need to turn and blast a block when the ghosts and salamander are upon you. If you are standing in one of the holes you made, you can avoid the salamanders fire by jumping right after he finishes firing, but before he falls in the hole with you.
First, run to the right and remove the two blocks beneath the upper right flame.
Then return to the basement and head left. Pick the left bell and break the block above.
If necessary, jump up to lure a gargoyle clearing the path.
Now lure both gargoyles past the lower left flame. Drop them to clear the path.
Climb up and remove the two blocks beneath the upper left flame.
From here, you can either drop the lower left flame, proceed to middle shaft, move upstairs and to middle of top floor, or take a detour and drop the lower right flame, seal the open shaft, and move through the middle shaft to top floor.
The rest part of getting the key and leave is easy. You may want to trap the demonheads coming out from the right mirror after obtaining the key.
Because of the key location, this room requires 2-cycles. You must place a block on the rightmost edge, 3rd space up, or you will not be able to make the 2nd cycle and enter the open door on one life.
Start your climb using the 2 blocks at the far right of the screen.
Place a block in the location mentioned above. You will drop the flame onto this block later on.
Use diagonal jumps to clear the 2nd flame.
Drop (as far as possible) the 2 closest flames to your left.
Place a block under the Kameera Mirror.
As you move back to the right edge of the screen, drop the flame located directly under a gray block.
From this point on it's fairly straightforward, but will require another cycle to drop into the open door.
This approach will allow you to obtain all bonus items, but does not allow for a safe return path from the extra life jar.
