I liked this. I thought it really evoked the feeling of the show. I thought the floor texture being static was a strange choice initially (although I know it's a limitation of the simple raycasting engine you're using), but it grew on me as I went through the level. The strangeness matched the tone of the show. The main thing I would change would be to not use any texture filtering on the sprites, as I think it would make the art style feel more coherent.
