tres cool, des mecaniques jamais vu

very fun roguelike deckbuilder with great soundtrack and vibes, took me a while to complete a run especially since i'm new to the genre but it's very entertaining

Great game, very competent and purely fun riff on StS. I honestly loved the way it pulls from Slay the Spire fairly openly but also has an immediately obvious hook with every deck being 3 colors. The characters feel really distinct and the mechanics are satisfying and all feel deep enough.

oh i forgot to log this sorry. game of the year

Me sorprendio muchisimo para bien, excelente juego, muy carismatica historia y perfecto balance de las cartas
Super recomendado


This is another deckbuilder I can manage. It's not the most complicated game, but there's a lot here to make fun builds off of. Playing in tandem with Balatro and there's a lot to enjoy in both the titles.
The vibe of Cobalt Core is spot-on. The music is excellent, and all of the remarks of the team you choose are hilarious. The game is fun too, I find that there's a lot to get out of this game if you want it to be super hard, and vice versa. Great!


More enjoyable game design than Slay the Spire, more personality and character, less visual and audio design polish. Very enjoyable. This might be my new morning game for a while.

hardest shopkeeper in a roguelike but i found an infinite

When I play a roguelike deckbuilder, the question I always ask myself is "would I rather just play Slay the Spire?". Usually the answer after a couple runs is yes, but Cobalt Core is a rare exception. It helps that it's clearly not a forever game, instead more of a Hades, where it is a straightforward story with an ending in the guise of a roguelike. It helps even more that it's extremely capable as a deckbuilder, using a lot of the fundamentals of StS but twisting it with a positioning system that actually works for once in this genre, and some really unique ways to switch up your runs. And then it's wrapped in the same charming character design, legitimately funny writing, and banger OST as its predecessor Sunshine Heavy Industries. Between that and this, I'm a forever fan of Rocket Rat, and will check out anything new they put out sight-unseen.

really cute, deep roguelike cardgame. The deck building potential is there and feels great when you get a broken combo. The game is a little slow though and ultimately didnt stick with me.

A fantastic roguelike deckbuilder + tactics combo that is sort of like Slay the Spire with touches of FTL and Into the Breach.

A little light on content but that's not a knock against it. The writing is surprisingly good and the characters and art are fun and charming.

Hope to see more from this dev in the future.

Great design, cool characters. Just didnt sink its teeth into me like some similar games have
