I like the idea and overall it feels pretty decent to play, but I think it's very punishing to play. I was being very thorough but at the last room I got farmed very quickly by the sword dummies. It felt like I had to find a way to cheese every enemy so I wouldn't lose all my health, like when the shooting enemies were grouped up I had better odds killing them through a wall instead of trying to find opportunities in between attacks (the lack of invulnerability frames definitely ramped up the difficulty). Visually and audibly, still very well done!
