Ohh! good, yes this is a game very good! I loving the is pluzze.

Teren excellent work and thank you for all the hard work you put into this guide for us. I tried not to use them but sometimes I needed them for a guide on how to go about things :) It really helped save my sanity.

I loved the game. Very fun. Disappointed that I can't seem to save my own scores? It seems that all the top agents are not me....Oh well. Still fun.

How do you collect the skelton keys? I have located some but can not collect them. What am I doing wrong? I click on them and nothing happens. Thank you for your help.

You can't collect them until the very last level.
