Ok, to begin with, this is one of the best code levels I played so far. Really great design, hints were really well portrayed inside this puzzle. I will give some hints for people, if you have troubles with it Spoiler: Hints 1)The keypad actually resembles something in real life. (Some of you might not know/remember it). 2) Each wall (3 in total) gives code for it's side in such order: brick block - grass block - brick block - grass block. 3) You have to decipher each symbol on the wall. After that you have to move draggables wich are connected with symbols inside the keypad (order doesn't matter), than you have to check, if you did it correctly.
Though, there is one flaw with your level, you can skip first 2 walls, without solving anything. Just small hint - you probably shouldn't put draggables close to the surface, since this is really bad combination.
I enjoyed this level. Original design and delightful gameplay. Spoiler I noticed the phone dial at first look. But I didn't realize the letters, because in Spain nobody used them. Only in SMS era, years ago...
