Were there any specific parts that you liked more than the rest?
I entered my name, and the characters knew my name. You saved it as a variable, I am easily pleased, sorry. Make the player feel they are in the game instead a set name. I hope that makes any sense.
Anything you especially didn't like?
I didn't know how to advance the story at first.
Anything you'd add if you were making the game?
Expanding from my previous answer, you can add an arrow to the left to the answers/options.
What did you think of how the additional story was integrated? Was it a cool experience? Did it feel awkward or confusing to play after the main story?
Cool yes, but it's not my genre to play. However, it doesn't mean it's a bad choice of game genre. One's opinion doesn't mean anything!
