Cobalt Core is a deckbuilding roguelike about some cute loveable characters stuck in a spaceship during a time loop. Each time you complete a run, you discover a little more about what's happening in the form of seeing a memory of one of the crew members X days before the loop began. The dialogue is brilliant and the pixel art style is lovely. I really enjoyed it for about 20 hours before it started to feel repetitive. It's a great self-contained game, although it doesn't have the replayability of Slay the Spire. There's some great original mechanics here though - 2 kinds of shields, different weapons, ship movement - all packaged into a deck of cards.
