Zarf/Andrew Plotkin has said before that he thinks about a certain interaction he wants players to experience in a game, and then builds the game around that.
This game was built around one interaction at the end. It’s a cool interaction, but the rest of the game doesn’t do enough to build up to and support this special interaction at the level it deserves. It’s like having a small 1-tier cake with a huge crystal wedding topper that it can’t quite support.
The cards were a nice visual feature: this is set in a futuristic Vegas casino, and you can see the cards being dealt.
Overall, this shows a high level of craftsmanship, and I anticipate that a longer game by this author would be great.
