### Texas Jigsaw Killer 25

Hi,

I've been taking an inventory of the walkthroughs on the forum and noticed that many of the earlier ones for TJK don't have walkthroughs.

This TJK #25 was very simple - I was really surprised. When I first started doing the TJKs I wouldn't attempt them unless there was a walkthrough posted that I could follow step by step. I just assumed that anything without a walkthrough was too difficult for me.

Haven't bothered with small text for this as it is an old one (as a side note when I was scouring the forum looking for walkthroughs I could follow I thought that the tiny text was some kind of special code that you needed to be a member to be able to interpret I know better know!)

Cheers
Caida
