Great program, thank you! I'm less than an hour into it, but it seems like just what I need for some board game design analysis. I was going to create my own simulation in Google Sheets, but this is definitely more fun! I haven't donated yet, but I will.
One minor request - "A > B" and "A < B" would be useful nodes. I know I can simulate "A > B" with "A <= B"-->"Not", but it's a little clunky.
