Balatro is fine. It has much more depth than something like Vampire Survivors, but exponentially less than something like Slay the Spire; I think overall it strikes a good balance. There's a lot of variety in the kind of decks you can build and how you influence the hands played, with most hand types being viable (straights still do not feel worth it though). After a couple of solid updates, there's also an expected and fun level of deck-building strategy you can employ with every run on all difficulties (high/gold stakes were previously re-roll RNG fests).

Once you learn the lay of the land though, most runs will easily devolve into the game-breaking dopamine rush that falls in line with the gambling aesthetic, which dampens the long-term replayability. It's most fun when you're still learning how it works, and after that, mid-run before your deck is fully fleshed out and the hand you play doesn't matter. One thing that I have zero criticisms of here is the stunning yet simple presentation; it has been tweaked and polished to premium-yet-retro perfection.
