Can't be harder than Myst IV, can it? :D
Or he gets Dizzy, because he just bought "Go Dizzy Go" in Nintendo store?

Everyone should....

The two questions I would ask are:

1. What is the first number.
2. What would cause the ninja to get dizzy.

Assuming I'm a nice person (and I am :p) the first action of the ninja is the first number.

i'd say 4, and spinning circles.

Well, the code just "in front" of the ninja is "Q5LU".

have you been at it the whole evening and got a mild migraine from it? then you deserve it too.

It seems your code proves to be too much of the challenge for these young ninja wannabes, nice job :)

Then Moto Racer 3 for me, thx :P

It's all about wrong way of thinking :)

dagnabbit just because i choose ninja hacking in school over this.

and you should have been here last week for moto racer 3 trid (and on sale) :p

So the key to the puzzle is what is first?

"ninja observes" is the first character of the code (not a chunk of the code).

If you don't know exactly what character that should be... perhaps his other actions can clue you in on what the first one would be?

There was riddle with MR3 as price? Now u made me very sad :/

well basically just a giveaway, think doc or namegoo gave it away yes.
are you just sitting there laughing your ass off at us being stupid?

Most likely :D

Maybe it's a language problem, but I'm not really sure what "look over" means. Look ahead of something? Look back to something?

laughing? no. Entertained? oh yes! :p

and again... I expected this would be much easier than it is turning out. It seems my inability to solves other's riddles has granted me a superpower ;)
Nope, you are overthinking. Since I've told you that each action is a piece of the code... take each action very literally.
