Slay the Spire, Monster Train, Balatro, and Griftlands have all proved just how compelling it can be for a game to combine deckbuilding and roguelike design. Cardstronaut looks to follow suit, taking a similar approach while adding in elements from the tower defense genre. It also has a novel hook, casting a hapless astronaut as the 'tower' in need of protection from an onslaught of deadly alien enemies. Now, thanks to a new Steam demo, you can try it out for yourself to see how its unusual mix of genres actually works in action.
