Check out this genre description: an action platformer with metroidvania elements, roguelike elements, and meta progression. Another description would be that this is a fast action game with deep and challenging combat that keeps you going with interesting unlocks over time. The world of Dead Cells is vaguely described by little nuggets of text found around the dungeons, but it is clearly secondary to the gameplay. Platforming that is precise and satisfying, and a combat system that seems inspired by the best elements of fighting games and action RPGs. In Dead Cells, you have the ability to cancel any action with a dodge (love it), the ability to switch orientation in the middle of an attack animation (love it), and every attack and status effect is clearly shown (which can be a bit confusing to look at in the beginning).
