Yeah, we've been hearing a lot that it's hard to keep track of all the characters. I guess personally I was never expecting the player to remember all of them from the introductions alone. It's there to give you a quick overview, not a cram session. (just my interpretation, I'm not the writer, haha)
We've had suggestions of a menu where you can see and reference all of them, and we're probably go with something like that in the future. Relationships will play an important role in the outcome, so it can all be tied together with a friendship menu. I'd also include the stats and routines and such info in there. I knew I didn't have the time to design / program that for this build, so it was cut early as an extra.
Thank you for your comments and suggestion and for playing our game ^^
Oh, as a quick fix, I'll add a visual reference for who is who on the game page. It's older concept art (and Nikolai changed his spelling), but maybe it will help.
