Tip about NC Sammy - if you don't let her enter in your office, then she leaves, but meter above her head start raising. When meter is full and you don't let her enter - she force door open and you get game over. Tip NC Maddie - actually around her card, you can accidentaly pull Sex card, which lead to game over. Fully RNG. Tip on Prinny - actually she boost or lower your corruption meter. Tip on Kass (marked as SC) - she has 3 inventions: station that send drone to deplet vent HP, crystal that drain your energy and green gates, that work as respawn point for girls(didn't actualy checked this, because I barely used coins).
