Developer removed Ren'py standards like fast forwarding and roll back. There's a screen to "choose appearance" for the LI but nothing there seems to do anything. The design of the LI looks weird in a semi-uncanny valley way I can't put my finger on. Dev claims Imouto supposedly has some mind breakingly deep personality development like an AI companion. Dev also can't prevent in-game days from looping or permanent soft lock states. Just bad all around.
