this a simple suggestion u can ignore if u wish.
to make the game better adding dialogs to the girls would be a nice addition, i suggest focusing on higher rank girls dialogues first and use an ai to speak the words the girls say so u can conserve on resources (cash and time). if you do consider this suggestion you can make it so that u can go down two paths for each girl corruption and romance and that each level of romance rewards diff interaction and diaglous and and vice versa for corruption. also make a personal place like a house that u can have either the girls u corrrupted completely or the ones u romance to maxed.
