I can understand your frustration.  But, just look at it!  The devs 
obviously didn't expect anyone to get through the game without using the "cheats" - as you call them (i prefer the term "walk though") - otherwise they wouldn't have embedded so many of them.
I have a suggestion for you.  Put Machinarium aside and go back to the Samorost series.  Play them in sequence, 
Samorost1 followed by 
Samorost2.  (for extra credit you could play 
Questionaut)  
That might help you see things from "The Amanita perspective".   

If that doesn't help, might I suggest 
DOOM?
