So if anyone cares, I caved in and bought it.
It’s a mix of Way of the Samurai’s action and sword fetish, Recettear’s debt-repaying shop sim and Shiren’s mystery dungeon roguelike.
It’s a bit barebones, but it’s kinda fun and does the job. It’s the closest thing to a Sekiroguelike there is right now, I guess. You can block at the perfect moment and go schwing and teleport on the other side of the guy and he drops dead. What more could you ask for? Don’t expect the same quality in the controls, though: movement is kinda slow and unresponsive and attacks don’t seem to have the reach they should have.
