Nursery School Escape

I went to my sister’s nursery school to pick up her.

I was waiting for a long time but no one comes out.

I went in to check out for her, but to my surprise no one is there.

I think she might have gone with my dad.

When I tried to go out, the door gets locked automatically.

I have to escape from this place.

Need Adobe Air Plugin to play this game.

Could you help me?
