Hi, thank you for your nice comment!
- The hand only ends immediately if the dealer show an Ace and has a blackjack, it is also used in real life blackjack (might not be the most common but still) :)
- There is no way to reset the entire game, I will add that in a future update!
- The "joker" style power of powerups is nice for sure (but it's also more work to implement).
Talented people have already done this with this game: https://purplemosscollectors.itch.io/dndg
(A blackjack game with Jokers/Tarots cards a la Balatro)
So I opted for a simpler way, but I might add Jokers/Tarots cards in the future, who knows!
