@,
It's amazing how people can have multiple pony OCs, hah. I currently have only two, one in which is a most recent addition to my list of OCs.
I'd love to offer feedback for Cero, do you possibly have some background info about him? (links to a bio, possibly?)
If I had to choose, the most difficult of the game for me would have to be...the Sketchbook map. Not only does the crayon theme hurt my eyes but I searched like crazy on how to progress until I gave in to reading a playthrough :v
My least favorite character from Ib is Ib's parents. Maybe most will expect Mary, but I don't see anything wrong with her (besides how annoying she may be, at least she has emotions. I only say hee parents due to how little background we have of them, and how their daughter ended up in a living art gallery where she could DIE in.
