Delightful mash-up of Zelda 1 and Castlevania! Music is also faithful to the genre.
I realize that it's an homage to Castlevania, but I'm a little frustrated by the sluggish movement in such a strictly timed game. Also, the floor tiles that contain a cross shape looked (at first) as though they might be interactable. But overall, the visual style was highly legible, which is not easy in 1 bit.
