Soul Crusade is a cheaper version of Dead Cells, with similar gameplay and graphics. (It's also NOT AVAILABLE ON IOS, IT'S GOOGLE PLAY ONLY!!)
While it's fun and engaging, it doesn't offer anything new or unique to the genre. The story and RPG elements are a nice addition, but it's not enough to make it stand out.
Unless you're really into the Castlevania art style or want a slightly easier version of Dead Cells, it's hard to recommend this game over its more polished and activly updated counterpart.
