found 6 discarded matches well hidden in the carpet.
keep clicking on the doorknob and you will get it.
make the matches into a star on the dark hole looking area in the corner on the first screen right from door. i can open the shades but cant seem to do anything with them yet.

ps. you will have one match left after making the star.

you need something to hold the shade up

use it to get the nail out of the molding in the screen one to the right of the window.

1. Click on the Bottom Right corner of the Right Blind to pick up a chip of the blind.
2. Turn Left once, look for a match on the floor, left hand side of your screen. Look for a 2nd match in the corner (center screen).
3. Turn Left once, look for a match just to the right of the hole in the corner. And the 4th match is just behind the hole in the corner (Center Screen).
4. Turn Left once, click on the doornob 11 times to unscrew it. Use the blind chip on the bottom left corner of the door. If the scrapings do not appear on your blind chip, they will be on the floor. Make sure you grab them with the chip.
5. Turn Left once, pick up Match #5 to the right of the corner (Center Screen).
6. Turn Left once, pick up Match #6 to the left side of the screen and use the doornob on the nail just to the right of the corner (Center screen). It is sticking out of the baseboard.
7. Turn Right 3 times to the Hole in the floor. Stick 5 matches around the hole. They should have to be done in a certain order, so if it won't go, use another match. When you have all 5 matches down, stick the blind piece with the scrapings on it.
8. Turn Left once, place the HEAD of the match in the keyhole.
9. Turn Right once, place the HEAD of the match in the pentagram. This should blow up the room. Ignore the blood, I'm sure it's yours...
10. You should now be facing the window. Turn Left Twice (Door) and look for the cobweb in the upper right hand corner of the screen.
11. Turn Left Once and use the nail on the center brick of the left most cluster of bricks. Take the brick.
12. Turn Left Once and use the nail on the center brick of the right most cluster of bricks. Take the brick.
13. Turn Right Once. Drop one of the bricks on the ground, place the nail on the brick, use the 2nd brick on the nail. Take the smashed nail.
13. Turn Right 4 times (To the window). Use the cobweb on the top of the left blind to hold it in place. Use the flattened nail on the handle and take the handle.
14. Turn Left Once, take the cracked baseboard from the corner here.
15. Turn Left Twice, use the baseboard piece on the wire beside the door.
16. Turn Left Once, use the handle on the brick on the floor, use the 2nd brick on the handle. Take the handle. Use the wire on the doornob, then use the handle on the wire ends (Strip them).
17. Turn Right Once, use the handle on the wire ends that are sticking out of the wall where you ripped the wire from...it's hard to see them. Look below the bricks left of the door. Connect the Doornob wire to the wall wire to magnetize the nob. Stick the nob-wire-tip to the base of the door to get the key.
18. Use it on the door, and you're done!

you can get a piece of the shade on the bottom right corner, keep clicking

get the door knob on the nail....

i can't get the head of the match to go in the keyhole or whatever...nothing is happening...i have done everything else up to that point...

you have to use the handle, not the doorknob, on the wires first so they go that orangey colour, then put the doorknob on to magnetise. I made that mistake for ages!

did you have to put the matches in a specific shape? what were the shavings from the door? what caused the explosion? why did you have to hold up the blind to get the handle? and why did a cobweb hold it up? why did running a current through the doorknob magnetize it? and why did you need a magnetized doorknob to get the key? and what was the key doing hidden in the base of the door?

Wires have 2 ends

You have to make sure you strip both ends of the wire, both on the doorknob and on the wall. Use the handle on both to strip. Now you will see orange ends on the doorknob in your inventory and orange ends on the wire in the wall.

The main character (you) was preparing to move out the room. When he was in the room, he accidentally dropped his keys outside the room and locked himself in the room.

Which means? HE HAS THE ESCAPE THE ROOM~ MUHAHH

So he looks around and found matches all around the place (because he's a smoker) An idea popped up and he thought about the rituals from the five pointed star. By making a five pointed star in one of the corners and putting scraps of dust (paint in this case, but think about it, dust is pratically made out of anything) into the center of the star then light it up, it absorbs the energy in the spiritual world and transfers as a physical energy in our world. However, the energy is too strong. And hence you see the blood. (or maybe the energy of the star saved him?)
