This is a really excellent first jam submission! Do ya'll already have game dev experience? Blackjack with a bit of a twist is pretty well scoped for a week. You've got great pixel art, fun music, and voice acting really stands out in a jam. I played some last night before bed and came back today and was very surprised to see saved progress too!
Some feedback from me: It took me a little longer than I'd like to admit to realize I had to click the deal button to start the game. I think I'd try something to make it more obvious like highlighting it or putting it center screen. The one thing that this game is missing though is in game sound effects. You have great music and voice acting, but nothing during the gameplay. Sound is the biggest bang for your buck you can get for game feel.
For your next jam, I think you should get some placeholder sounds in early. It's tough to do sound implementation if you leave it for later, but it becomes really manageable if while you're making mechanics you add placeholder sounds in. It'll make your game feel better instantly, and it's much easier to go back and replace the sound file rather than do the whole implementation, and you won't forget about it since you'll hear the placeholder sounds in development. Also generic placeholder sounds are often better than no sound at all if they make it into submission.
Very impressed awesome job!
