Thank you for playing and for the kinds words :) It's so nice to meet a friend of Luca's! Actually, the first simulation I ever attempted was inspired by Luca's amazing work on Madrigal's Simulators. Fortunately for me, that first simulation of mine wasn't very good at all, and after reaching out to Luca he was kind enough to help me improve on it. Since then he has generously provided invaluable support on many other simulations in this collection and I don't think this collection would be half as good without his help!
