1. You can't do anything at this point. Turn around..girl! Click the girl. She wants her RING.
2. She disappeared..weird. Turn and get the RUSTY NAIL from under the bench, then get the ticket using it.
3. Read the note. It could help.
4. Turn again. Take the BROOM. Turn again, take the box out from under the bench. Look inside, take the MARKER.
5. Turn twice(we're turning to the right always.) and zoom in on window. Break window with BROOM and draw on window with MARKER.
6. Zoom out, go down to cage. It looks like a pet rock. Click on the bars in the above mentioned number order. (1-10 going right) Click the front and take out the CLOTH.
7. About item the CLOTH, click once and get GLOVES.
8. Alright..ladybird code. Supposedly there are some by sunflowers but I only can find the two sets because there ARE no sunflowers..so just use the code 23816.
9. Take SIGNS. They don't seem useful right now.
10. Turn to the bench with the unbroken window. Click the top, get BOTTLECAP. Looks like a pepsi one.
11. Go to trash chute, hit it with the broom, use bottle cap on GUM. Get STRING.
12. GO to trash chute. Click the sides.

14. Put the CAP in the window(the open one.)
15. Zoom out, zoom in.

crow garden(Again, Lukasz.)
22. Move that sign. Power cables! Let's lick them! Oh..we can't? Use the GLOVES on the red wire(don't cut the blue wire!!), take the sign.
23. Cool, it's a mirror on the back! Use it on that hole under one of the benches. Take the box.
24. Zoom in on the box. Color the diamonds.
Blue Orange Yellow Green
25. You get a RING.
26. The girls' back. Give the ring to her, she get's all surprised, click her. (Note: Sanatorium has nothing to do with insanity. It's where people with really bad diseases go. Like tuberculosis. Even depression got you in there.) She disappears..
27. Go out the door. Normal end. I'm working on figuring out Happy ENd.
