Loved it! I really liked how you turned Monty's hall problem/paradox into a game! It's simple but I really enjoyed it. Aaaand, it also works to teach people this concept! Double points for that. I love the old windows art style, it looks super good, and I feel like I'm back in 2004 playing pinball in my family laptop. The audio matches the vibe really well too.
I just have one question, is the game coded so that if you swap your choice, you always get the golden calf? Cause it always happened, even when the odds where against me with many doors! If this is the case it's gonna be a little easy for people who know this problem like me. I guess in that case the game would be much more suited for people who don't know how this works, and therefore will be tempted to keep their initial choice and not swap it.
Still, even if that's the case, it's an enjoyable game :D
