Im giving this game three stars...but I want to give it more. 

Firstly, let me say the voice acting was amazing! You could not have done any better! 
The game is beautiful, like really damn good looking! 
I think your story hits the purpose right on the head of the nail! I fully understood what was going on! 

But the clues...
Some spoilers real quick!! 

The first clue made no sense to me....add the first two digits, call me....the answer to that riddle was simple, but it wasnt the answer you wanted...therefore the riddle was...too confusing. How would you be expected to dial the rest of the answer when the riddle only wants to know the first two digits added together? Your next riddle was great, infinity? OH MAN BRILLIANT! Had the answer to the first riddle just been what was asked, this game would be amazing! Took me forever to realize what was wanted in the input. 

Fix this, or at least be more clear next time, please. I want to play the rest of this!
