Looks great and it is very well made and polished. I like the transitions a lot, especially the first time you enter the table scene. The mechanics felts good and snappy, though sometimes the "hitboxes" for where to place a card were off (especially when the dealer places their 3rd card). I like the idea for the core mechanic, I'd definitely be interested to see it implemented.
Here's some other feedback if you make a full game:
- The mouse cursor follows the real mouse a little slowly. I'd like the options to make it faster, or just have the base value higher, as it feels unresponsive
- The draw pile feels a bit odd, especially when waiting for it to refill. Could it just be a stack where you always take the top card, and not redraw? Not sure it this would have tied into the cheating, like be able to peak ahead/reorder
- Could some of the dealers actions be automated? Dealing the 12 cards out is fun enough, but if the game had other actions (like cheating), this seems like something that could be done automatically and let the player focus on other things.
Good work!
