i've never played this game. Are you really that green character in this, cuz that's kinda lame.
For most of the old H-scenes, yes, the MC is replaced by a coloured silhouette. However, as an RPGmaker game, your character has his own sprite art and face design (the red head guy), and all the new h-scenes in the game (Diadira, Orange Girl, Pandora, Nerys, Natya, Miri, Doralice) have proper art with him rather than the old 3d art. They are also retroactively replacing the old scenes with updated art, but so far have only managed it with Larelle, Elaiya, Theresa, Yamamaya and Alina. The plan is to eventually replace all old scenes with the updated art, but that's a long way off completion yet.
