Ton of complexity to break stuff with. Also has a lot of things to unlock through runs and playing and gaining exp. This is a pro for me but I also know a lot of people don't like that kind of progression.

This game is absurdly strange and unique. And let's face it: it markets itself very poorly, because it doesn't explain what makes it unique. Think of any rogue deckbuilder; the basics are pretty much the same, it even resembles the old Hearthstone. But that's where the striking difference comes in: the cards grow, in various ways. The game introduces several "lasting" effects that change the values ​​of your cards until the end of the run. And this changes practically everything in the game; it's not just about winning battles, but about making the most of them, growing your deck. Both creatures and spells can and need to become stronger. And that's what makes the game fun and each run unique. If you like deckbuilders, this game is a very safe purchase.

Game is actually good so far, the good parts of Hearthstone with typical deckbuilder/roguelike-lite elements of "Play game, get rewarded with more cards + people to play." Genuinely just fun. I'll update this further once I play some more but so far so good and characters are honest to god attractive which also didn't require a consolutation fee from nuclear hazards. Related to the game topic/rant: I just came on here to put another good review because whoever the dumb ♥♥♥♥ that is the negative reviewer called slightlyundead is either ragebaiting or genuinely braindead. It's literally got a metaprogression of XP, you get MORE ♥♥♥♥ by playing the game. It's just a different currency than other games that might use "shards" or "coins", I'm not defending how tags are used but look no one knows how to apply these tags properly nowadays to begin with. Greatest example is people apply the "Durr, it's like slay the spire" and the only thing remotely similar is the deck building aspect. Just call it Spirelike atp, every dumb ♥♥♥♥ does it with dark souls and armored core. May as well redditify that tag and genre too lmao.

Good first impression, having fun, recommended. Mostly writing this review to offset the negative rating by slightlyundead though. Reading that review gave me a cortisol spike, so here's a quick rant: All the big roguelike deckbuilders have roguelike AND roguelite in their tags because those genres are extremly loosely defined (StS, Balatro, etc.; btw none of which are from Chinese companies). Back in the day they just meant, games that actually are kinda like rogue, and (for lite) games that have permadeath and proc gen but are actually action games or some other genre and not really all that much like rogue outside of those mechanics. Also why in the everloving love of good games would you expect this game to have metaprogression that makes you stronger, when none of the big games of the roguelike deckbuilder genre (and none of the smaller ones I've played for that matter) have that? Giving a negative review because a tag has a specific meaning for you that the majority doesn't really agree on, is big brain energy right there. Also, good stuff, making a hot take like that and then disabling comments. Anyway, rant over, game looks great. Will play more. And also, really glad that it doesn't have metaprogression that makes you stronger.
