The narrative got a bit dark for me in that I felt a sense of whiplash, from kind of "sensible chuckle" to extensional crisis very quickly.
I think the theme came across best with replacing labels with unlocalized keys. It was the first thing that was like "ah, I see where this is going". Also I'm not sure if it's intended but unity has definitely trained me to see that magenta as a missing texture bug as well.
Most surprising is just from the screenshots how I've just been trained to assume a reigns UI instead of just clicking on cards.
I feel like this is one of those games where you made the game you wanted to make and it fits together in it's own way. I had a lot of trouble seeing the text on the cards I was selecting after the snake game, so things got a bit random for me there.
Meta bug report: There's a typo in your description. "Loose the game" instead of lose.
