The only mistake is that you can cheat by just trying possible combinations and check if the numbers grey out. It should be made so that they always grey out if the line is POSSIBLE according to them, not only if it is CORRECT. Otherwise, 5/5
As the Ending scene went one, noticed how that other golden acorn landed in front of the girl right on top of the now-unreachable ledge? Play through it again to see the SECRET ENDING!
I found the Assault Rifle to be a little overpowered, especially when buying fmj early. Otherwise, a real gem! I liked the notes a lot! Especially the "chatlog" one, 0/5 needs badges! :D
