A fun little game! As far as I can tell, it shows you how to accomplish quite a few legit card sharp techniques, which is cool. The setting is neat, and the characters are all quite fun as well.
The one stumbling block is that it has the "Math Test" problem. That is, you are taught the basics of a technique, then under pressure have to reproduce them. This is fine at first, but then twists and variations are added which, in theory, are merely applications of what you already know. In practice, the game never gives you a good enough grounding to feel confident in these new techniques. And it's asking you to do them for the first time with a lot on the line. The second-to-last sequence is the only one where this is a big problem. I had to attempt it three times, failing and getting a game over each time. By the way, the game over screen is cute, but tedious in repetition.

That is a long paragraph for what is ultimately a small complaint. It's a fun game! Worthy of being checked out by anyone.
