Has anyone got the blackberry app ROOM ESCAPE?

Hi, I downloaded a game called room escape on my blackberry yesterday and have played it for hours on end and all u can find in the room is a blue triangle, a piece of paper with grid drawn on it, a stick and a piece of green paper. I have searched the room and cant find anythin else. The only thing I no how to use us the blue triangle. If anyone has got this game and has been ableto get any further I would really appreciate any help anyone can give. Also if anyone knows a site that has a walkthrough for this game that would also be really appreciated. Thanku ,:-D
