I don't know if there's a place to give grammatical feedback, so here it goes. I only noticed this because most of the writing is well designed, and the proofreaders do a great job.
I think it's supposed to be: "Too bad I still barely have any idea on how to control any of the characters."
An even easier way to do this would be:
"Too bad I barely know how to control any of the characters."
Since the sentence above already sufficiently establishes the precedent set in the original sentence. Sorry if I'm coming off as snobbish, as that is not my intention. I'm enjoying the game a lot so far! Keep up the good work!
