Nice work! Just a quick suggestion, there's a possibility for Katarina and Emma to stay with you even after taking Mario down, after the two scenes of Katarina with Mario you can find her in the pool/terrace 3 times, she'll fall for you at the third time and won't be mad that you get rid of Mario, with Emma you can seduce her and when the you get with her you can tell her she needs to resist the temptation, after that she can help you, that way you can enjoy both of them even after taking Mario down
