Thanks a lot! I felt so stupid when I found the red block just hiding in the corner! Lol

Where do I use the spray? And I've been stuck on this code/lock thing for days! Help please!

Go to chapter 1 walkthrough, there's a pic posted on how to solve that puzzle

go to Chapter 1, lol there's a screenshot of that problem.

Im missing one more block to complete puzzle, and im having trouble figuring out the 4-digit code :(

Where did you use the spray for?
