Really cool concept! Depending on what you like the game to be more, puzzle game or like turn based fighting. A time limit per turn might be a neat addition. So far it feels like going defensive seems a steadier strategy than going offensive. While I personally love crits, I feel picking those artifacts at this moment without powers to help you get comboes, flat attack might always be better. Hope you keep working on this game because I really like where it is going :D
