Edit: After writing my review, I did actually play run after run after run... I could not put it down until I had finished the story! Original review: I occasionally pick this back up and play a few runs. I am a bit burnt out by the deckbuilder genre, so I am not inclined to play run after run after run. That said, Cobalt Core is great, honestly one of the best in its space. Pun intended. Mechanically it's exactly what you'd expect, but it's flavored really nicely and has a lot of character. The UI and sound design make the game feel really snappy and satisfying. Also, the writing is genuinely good, and the characters are really cute and likable. The music is not for me though, I have it on mute. Cobalt Core is a very smooth and good looking game. If you are at all into the roguelike deckbuilder genre, you should not miss out on this one.

finished my first run. Usually counts as a negative if I win my first roguelike run, and I did here (finished first run and came to review). just shy of an hour and a half for the run time, so a little short and not sure how different runs are. but was fun and felt like a merge of FTL and StS but a bit easier.

A deckbuilder whose cute and simple-looking exterior belies a more intricate and deeply interesting game. Appears to be inspired by FTL and Deckbuilding genres, with some extra twists and tweaks. The game has you selecting a ship and various crew members at the start of a run. Your crew members, such as pilots and weapons officers, will determine what kinds of upgrade cards you get. Meanwhile, on the battlefield, positioning matters as your cannons and launchers will point at one segment of the opponent's vessel while theirs does the same to you. This leads to some pretty interesting choices before the game (which crew do you select), in battle (do you need to move now or should you fire and risk return damage), and deckbuilding selections (if you add this attack card, for example, will your movement cards now come up too infrequently?). Soundtrack is pretty nice and worth purchasing too. There is a story and humour inside, and some amusing interactions between the characters as you play, though even if you were to come back after quite some time off you can focus solely on gameplay and still have a good time. I like it a lot, it is staying on my Favourites list, and I would like to play more often.

now that i have completed this game's story and near 100% it (There's an achievement to complete [not win] 30 daily challenges, the point is that I have played more than enough to confidently say that... Cobalt Core has become one of my, if not my #1 favorite roguelike of all time. (The other games on that list are Noita and One Step From Eden. Just for reference's sake) Like, i just love this game on so many different levels. I love how you can mix and match your starting deck via choosing which 3 characters are aboard your ship I love the soundtrack and I love how the soundtrack smoothly glides from one track to another when you move in and out of combat. I love how each character has a unique personality with dialogue that is relevant to what is happening in the game all the way from which characters they're paired with, how many cards are in your hand, what kind of attacks they're being faced up against and what statuses you currently have. It makes the game feel much more alive and it's executed extremely well. (I <3 Riggs, she's pawesome sauce) (((I also adore the small pixel versions of the characters that you see during some cutscenes). I love the atmosphere of this game for its "cobalt" coloured everything, light hearted story with serious elements and blah blah look i really like time loop type stuff and the fact it links into the roguelike aspect really well is nice. I love how the gameplay allows for many different strategies which are all viable in one way or another. even the micro stuff like deciding if you want to use your last mana on a shield or dodge stack can dramatically change how the battle turns out. I love that and it was extremely rare that i felt like any loss of a run was due to being unlucky. Every run is winnable even on the hardest difficulty (which i exclusively played on) I have criticisms, of course. I wish the game was longer and that there were more characters/decks/cards/artifacts. but you get well worth your money's worth. Sometimes you do lose because you are unlucky, but this is extremely rare relative to other roguelikes. I think the earlier difficulties are way too easy until the hardest one, but I understand that it's a subjective thing and I enjoy that the difficulty you play on provides nothing but a harder experience. You are not required to play on anything in particular for any kind of purpose, so that's great. Point being that near every drawback i can think of that i'd begin to care about is also handled and balanced really really well. (I can make a case for Max's cards being the only ones that care about positioning (except for the tideturner, but that's a ship). It'd be cool to have a peri card or two that care about if they're on the left or not, or a drake card that does more damage if its in the dead centre of an odd numbered hand. but realistically it matters soooooo little, y'know? I also wish that evil riggs was playable haha. oh and some combos of characters are very difficult. but also i play on the hardest difficulty and plus i personally enjoy challenges.) Look the tl;dr is that I personally find this game really really charming and its gameplay/strategy really open-ended + deep. The ending made me cry and I just have a huge amount of love for everything about this game. I'm extremely grateful for this game's existence and as corny as this sounds, it has changed my life <3 oh and it works well on linux

Where do I begin here? A neat little roguelite deckbuilder with a gimmick to differentiate from the others. This is not the first nor will it be the last in a literal swarm of games covering this genre. But there's something different, something special about this little title. The game is a bit short for my roguelite tastes, getting to the final ending after a minimum of 18 runs. But the replay-ability is plenty high to go back again and again and try out different ships, different pilots, different modes, etc. The story itself isn't particularly deep, but it has its charm and humor. Some of that may be hard carried by the following bit: The music. Aaron Cherof, take a bow for this magnificent work. Possibly my favorite indie soundtrack of all time, and definitely in the top 10 without a doubt. Swerving through quiet mystery, poppy little combat music for the weaklings, intimidating and aggressive for one boss, and emotional buildup for another boss. The finale made me cry, which is saying a lot for how little time you get with this cast. Self-defense and the ending songs are the highlights but the whole soundtrack is a platinum star. But if you like deckbuilders, or if you like roguelites, or if you like A.C.'s work in Minecraft, or you want to see a possum with a gun flying with reckless abandon, this is a game that should be at the forefront of your radar.
