Much Characters were removed because of Rights to Lip or some Things between Mofu and Lip what is private. At some point Mofu didnt even had a choice or else there wouldnt be a game
I know that 4+ characters got removed due to things between Mofu and Lip i did do some reading in the comments here and the patch log after seeing the page had changed.
And even though it's sad to see the characters (for me mostly Ophelia and Raccoon girl) being gone but still im very glad that Mofu decieded to remove the characters and keep the game alive and continue working on it instead of picking option 2 and abandoning the project.
