Boo-Balu

I am locked, between four walls... Many walls! I dont see the exit, I cant even see where I enter, I dont know how I got to this place or why Im here... The only thing that I know is that I must collect them all, maybe this way, somehow, I can find a way out. I see that I am not alone, I am scared, they look like tissue ... or are they ghosts? is that a flan? I better not make contact with them... I hope I can resist. I am very nervous I wish I had gum... ♥ 10 levels ...Avoid touching the ghosts...
