Yeah, it preceded balatro for its demo. I still think it's a fair comparison because it uses a card game as the framework for a game, but dndg diverts even further from blackjack than balatro does from poker.

Negative cards and cards that round up are great. You want to cycle your deck as much as possible because then you can use your like power cards more. I try to remove any standard face card and high cards asap.

You can also easily fuck with the enemy by changing their cards/deck, like using the limit break type card to double the value of something high and then locking it so they just automatically bust.

Btw There is a new public beta you can use which fixes some issues and makes the early game a bit smoother and healing more plentiful.
